FC017 Sketcher Bug deleting constrains

[easyw-fc]

Hi,
in FreeCAD_0.17.12090_x64_dev_win if I try to delete a simple constrain in Sketcher I get an error and FC become unusable

Unknow C++ exception

In previous releases this was fine (0.17.12018).

...thanks for the warning - waiting for next FC.17.12xxx.
Only a delayed download saved my day.

Hello,

I have same problem on Linux with FreeCad compiled from Git , on two different computers.

OS: Ubuntu 17.04
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.12087 (Git)
Build type: Unknown
Branch: master
Hash: e70a1678f8f19c3725d3b3e4f0b165f2c6edfc84
Python version: 2.7.13
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.1.0
Locale: English/UnitedStates (en_US)

In my case, if I delete any constrain from sketch, Freecad just crash. It also happens if I draw some sketch, add any constrain and press Undo (or Ctrl -Z). It happens every time.

If started from command line, it crash with:

FreeCAD: /usr/include/boost/smart_ptr/shared_ptr.hpp:710: typename boost::detail::sp_member_access<T>::type boost::shared_ptr<T>::operator->() const [with T = App::Expression; typename boost::detail::sp_member_access<T>::type = App::Expression*]: Assertion `px != 0' failed.
Aborted (core dumped)

In Freecad daily 0.17.12018 it works, but in Version: 0.17.12078 it is also crashing.

Backtrace is in attachment.

I can confirm the same error. Freecad crashes after deleting constraint 6.
