Mod pluginloader InitGui.py starting ...

During initialization the error local variable 'fn2' referenced before assignment occurred in /usr/lib64/FreeCAD/Mod/plugins/InitGui.py

-> Select Edit -> Preferences

Then the application hangs for may be 3 seconds and then the application crashes.

I can't reproduce this. My version info:
OS: Ubuntu 16.04.2 LTS
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.10473 (Git)

I see you have some addons installed:
Mod pluginloader InitGui.py starting ...
pluginmanager config file /home/bb/.FreeCAD//Mod/plugins/pluginloaderconfig.yaml
During initialization the error local variable 'fn2' referenced before assignment occurred in /usr/lib64/FreeCAD/Mod/plugins/InitGui.py
To troubleshoot, can you try temporarily moving the contents of `/usr/lib64/FreeCAD/Mod` and `/home/bb/.FreeCAD/Mod` to different folders, e.g. `/home/bb/system-mods` and `/home/bb/user-mods`? That way we can see if this is occurring because of, e.g., an old version of an addon.

Tried this:
- Moved `/home/bb/.FreeCAD/Mod` away -> still crash opening the pref-dialog
- Moved the central `/usr/lib64/FreeCAD/Mod` away -> Crash vanishes, the dialog can be called
- Deinstalled complete FreeCad via rpm-mechanism -> the whole /usr/lib64/FreeCad - dir is deleted. Reinstalled FreeCad from packman -> /usr/lib64/FreeCad including the Mod-dir is of the packman-installation
- Crash is there again.

So, I would conclude, there is something offending in the Mod-directory of the packman package...

OK, I narrowed it down a little bit:
The crash vanishes if the directories /usr/lib64/FreeCAD/Mod/Arch and /usr/lib64/FreeCAD/Mod/Draft are moved away. If one of these two dirs are avaylable, the crash occures...

Here is the output of ldd /usr/lib64/FreeCAD/bin/FreeCAD

Might be that one of the referenced libraries is not compartible?

What workbench do you have active when the crash happens? Is it possible to change to any other workbench and not have the crash? Can you try temporarily moving the folders needed to not get a crash and change your startup workbench and see if that has any effect?

I have played arround a little bit with the workbenches: No change of workbench leads ever to a crash. I start with the "start" - workbench

But gunny behavour:

  1. Start-Workbench -> Open preferences -> Crash
  2. Start-Workbench -> Switch to "Part Design" -> Open preferences -> Crash
  3. Start-Workbench -> Switch to "Complete" -> Open preferences -> NO Crash
  4. Start-Workbench -> Switch to "Complete" -> Switch to "Part Design" -> Open preferences -> Also NO Crash

I also run a "strace" of the crash in case 1) which I added here

I have updated my system in between, but the same error is still reproducable.Please find the strace attached.

@bernhardb Can you update to the latest 0.17 revision and retest?

@Kunda1
That is the newest version of the packman package. The system updated it a week before or so.

@bernhardb can you still reproduce on the latest 0.17 ?

reporter   ~0009748

@Kunda1
I really think, the problem is not in the source code of FreeCad, but in the build process of the packman-suse-packages:
If You look at
http://packman.links2linux.org/package/FreeCAD
they were newly uploaded today. But they are - like the version number shows - still based on the source code of the date 2017-02-22. So, the distro recognizes the new package but installs a build of the old git status again and again...

@bernhardb can you let downstream packman-suse package team know this is a problem ?

I just opened a ticket downstream: https://bugs.links2linux.org/browse/PM-140 and have asked on their freenode #packman channel for help.

reporter   ~0009755

They closed the downstream ticket with the comment that the maintainer left the project and they will withdraw the (non-functional) package. So, I think, this ticket can be closed too: This was quite shure only in this package a bug, and since the freecad-packman-package seems to be dead there is nothing more to test on SUSE linux.

Thanks for the whole work!

@bernhardb We have appimage builds https://github.com/FreeCAD/FreeCAD/releases/tag/0.17_pre that work cross distro. just downlaod the .AppImage and make it executable. Take the larger file from the link. The other is an old build that has netgen support. If you get a crash please report back.
