Kicad crashes when opening Footprint library editor

[staviq]

Kicad on crashes when opening Footprint library editor, with: Assertion failed: (dims.x != 0 && dims.y != 0)

Happens on OSX, not tested on windows.

I do not remember fiddling with any footprint library, just to make sure, i have recompiled from source with mac builder, and reinstalled kicad, But no luck.

Steps to reproduce:

1. Start Kicad.
2. Click "Footprint library editor"
3. Loading windows appears, and when the progress bar reaches 100%, the Kicad crashes.

According to the crash report, it happens somewhere in opengl init functions, except accelerated toolset in pcbnew works fine, so opengl and gpu seem to work fine.

Just to make sure, i have tried this without a second display, but no luck, still crashes.

No problem on Linux, might be macOS specific.

@Orson, try sizing your Footprint Editor as small as it will go, quit Kicad, and then try it again.

@staviq, go into ~/Library/Preferences/Kicad/pcbnew and delete the ModViewFramePerspective item. (It will be 5 or 6 lines long; basically everything from ModViewFramePerspective down to but not including ModViewFrameMostRecentlyUsedPath.

Let me know if that fixes it.

That's odd. Can you change the anti-aliasing setting to supersampling and see if that changes it?

I cannot recreate on my Mac (admitted not as up-to-date)

[Seth Hillbrand (sethh)]

I take it back. That did it Jeff! Good catch.

[Jeff Young (jeyjey)]

You were nearly there, Seth. One more step from the antialiasing initialisation would have taken you to GetClientRect() returning {0,0}.

I’ll push a fix shortly.

@Jeff

I do not have any file in ~/Library/Preferences/kicad containing "ModView"

However, i did rename Kicad preferences folder so it resets, and when i opened Kicad, the footprint editor did not crash, so you are definitely on the right track.

Just in case, hare is my whole kicad prefs folder.

[Jeff Young (jeyjey)]

Odd. (I made a mistake and meant to say ModEdit not ModView, but you don't have any of those keys either.)

Anyway, you can also wait for tomorrow's build and then revert your Preferences folder and it should handle even the bad data.

[staviq (staviq)]

I have reverted my prefs folder and recompiled from master and it works, so i guess your patch did it.

Thanks !

[Jeff Young (jeyjey)]

Cool. Thanks for reporting back.
