Ubuntu 20.04 LTS, both stable and daily have the same issue.

Steps to reproduce:

2. Click "create new"
3. Switch to part design WB
4. Click "create body"
5. Click "create sketch"
6. Double click sketch in tree view
7. Dialog box comes up that says "a dialog is already open in the task panel, do you want to close this dialog?". Click yes.
8. Freecad segfaults, I get this on the terminal:

Wizard shaft module cannot be loaded
Program received signal SIGSEGV, Segmentation fault.
/tmp/.mount_FreeCAzusWhD/AppRun: line 46: 32587 Segmentation fault (core dumped) "$PREFIX/bin/$name" "$@"

---

ALSO I get a lot of error messages when starting freecad, regarding numpy. Here is what I get on the terminal:
Path WB not found
During initialization the error "

The crash has been fixed with the above commit.

The Numpy problem is caused by conflicting Python version of your local site-package (3.8) and the one running in the AppImage (3.9). I am not sure how to solve this. I'll need to search around for some answer.

PS. next time, please try to split the issue for each problem you have. Thanks!

Hi @looooo, could you please take a look at the above Numpy version mismatch problem? Any idea on how to solve it?
