[krushia]

Is there an existing issue for this?

• I have searched the existing issues

Problem description

1. Use AppImage
2. Open addon manager
3. Make sure it is set to show macros
4. Find ObjectsToPython
5. Click it
6. Watch rapidly changing line of text
7. Click back
8. Segfault

Program received signal SIGSEGV, Segmentation fault.

Everything except the segfault happens with my manual build.

Subproject(s) affected?

Addon Manager

Anything else?

Visually it seems to be stuck in an endless retry loop, which might be related to FreeCAD/FreeCAD#15059

Not sure what's really going on.

I cannot reproduce this on Windows and macOS with the latest weekly.
Does this still happen with the latest weekly AppImage?

[luzpaz]

@krushia can you still reproduce ?

[xtemp09]

Some update of this post must take place. For some reason, I cannot reproduce the crash with my manual build, but, I can reproduce it with a weekly bundle.

Still happening. Again also confirming it only crashes with the AppImage, but the manual build still "misbehaves" in the same way except it doesn't crash.

Can you please retest on latest dev again? (not that FreeCAD/FreeCAD#15059 was fixed)

Aside: this ticket troubleshooting process would benefit from FreeCAD/FreeCAD#15710 being implemented.

[krushia]

Crash still happens. Seems to be faster now... Also, I should clarify that I have that macro installed already. The crash doesn't happen when trying to install it, but when viewing the page for it in the addon manager.

Whatever was causing this was probably fixed by #169 -- if that turns out not to be the case, please re-open.
