crash when I open a file

[sket]

Hi all, I have updated FreeCAD and now it crash when I click on a file o folder of the pop-up window to open or browse a file.

Do the following from a terminal window:

Code: Select all

gdb freecad
run
# let freecad crash
bt

Report back the output. Btw, what was your previous FreeCAD version?

[sket]

sorry, but I don't know what I do, anyway:

the Software is blocked with the pop-up window to browse file open, so I try with other command and I have this

That's what I have expected. So, it's not a FreeCAD bug but an error in a 3rd party module which the system also loads when opening the file dialog.
To fix the crash you have to un-install the package qt-at-spi

[sket]

thanks, I remove the pkg and now seems all ok

[NormandC]

Would it make sense to prevent the FreeCAD package from installing if the qt-at-spi is found?

[Crossleyuk]

Sorry, very inexperienced outside general Freecad and Paraview modeling operations.

I have the same problem. Freecad crashes whenever I open a file. I cannot open any file. I had not made any changes or added anything from addon manager, the problem just started after I restarted work on a model I've been working on for weeks.

The other problem is that Parview will not start at all.

I have uninstalled Freecad and Paraview and reinstalled both but nothing has changed. Freecad fails when I open a file and Paraview will not open at all.

I have no experience other than building models.

I cannot get the latest data but this is what I had when everything was working okay

Can you try with latest stable version - 0.18.2?

I have the same problem. Freecad crashes whenever I open a file. I cannot open any file. I had not made any changes or added anything from addon manager, the problem just started after I restarted work on a model I've been working on for weeks.

The other problem is that Parview will not start at all.

Firstly I'll put the Paraview fault to one side for now and just concentrate on getting FreeCAD to load cleanly. This is the procedure I've put together, I've tried to make it easy to follow, I hope it makes sense:

1) Rename C:\Users\username\AppData\Roaming\FreeCAD\Mod folder to oldMod
2) Rename C:\Users\username\AppData\Roaming\FreeCAD\user.cfg to olduser.cfg
3) Rename C:\Users\username\AppData\Roaming\FreeCAD\system.cfg to oldsystem.cfg
4) Start FreeCAD and check Report View is open at the bottom right of the FreeCAD main Window, if not, click the View menu > Panels and ensure Report View is ticked. This is so you can copy an errors for feedback if required.
5) In the Start Center (Start Wb) there's some Example projects, click the 'Load an FEM 3D example analysis'. If the file doesn't load then you'll have to report back as this is the most simple config I can think of.
6) Close FreeCAD
7) Rename C:\Users\username\AppData\Roaming\FreeCAD\oldMod folder back to Mod (this will enable all the AddOn Workbenches)
8) Start FreeCAD, do you see any errors in the Report View? If not, then go into Edit menu > Preferences > Cfd and copy and paste the folder where you have OpenFOAM installed e.g. E:\Program Files\blueCFD-Core-2017\OpenFOAM-5.x and Run Dependency Checker, Click Apply and OK to close the Pretences window
9) Try opening the attached CFD_Elbowstage2.FCStd file built with the previous CfdOF Wb and loads fine on my PC using 0.17 with the matching previous CfdOF Wb.
10) Assuming FreeCAD is still working fine then you can retry opening your project file. If your project file causes FreeCAD to close (crash) then hopefully you have a backup file generated with the same name but with .FCStd1 extension (this should be a version that saved cleanly before all this started). You will need to rename the faulty FCStd file first and then change the extension of the FCStd1 file to FCStd.
11) Start FreeCAD and try to open your project file.


@kisolre, normally I'd fully agree with your suggestion of trying the later version of FreeCAD but in this instance as there's been recent changes to the CfdOF Wb and as this is one of @Crossleyuk's main uses I think it's best to get this working first. By the time 0.18.3 has been released do the upgrade then otherwise there'll be too many variables to comprehend what's going on.

You can try to reset the configuration with the button in the preferences. Another possibility is to delete your config files or to move them in case you want to restore them.
