(pinta:2): GdkPixbuf-CRITICAL **: 14:34:26.132: gdk_pixbuf_calculate_rowstride: assertion 'width > 0' failed

(pinta:2): GdkPixbuf-CRITICAL **: 14:34:26.132: gdk_pixbuf_calculate_rowstride: assertion 'width > 0' failed

after that "GdkPixbuf-CRITICAL" errors Pinta's still working.

Version
OS: Debian 12 bookworm x86_64
Pinta ver.: 2.1.2 from Flatpak

EDIT:
I'm using KDE 5.27.5 in Wayland session. And my videocard is AMD Radeon RX580, if it's important.

Thanks for the report!

Those "GdkPixbuf" messages are unrelated / harmless, I think, and show up normally.
It's very odd that there isn't any stack trace from the crash, though, which makes this very tricky to diagnose. I don't think I've seen any similar reports to this

I'm not sure offhand if it's possible to run a debugger like gdb on a flatpak process, but using that to see a stack trace of where it's crashing would be helpful.
I suspect there's something happening on the GTK side of things, since a hard crash like that most likely is from native code.

You could try to use a GNOME session and see what happens.

Of course I can't, GNOME will ruin my whole system, including KDE.

I am experiencing the same issue although when I launch the app I dont even get a window. Running most recent popos trying to launch via console in verbose mode gives me this

manually reinstalled canberra-gtk-module via APT and rebooted system to be safe issue still persists

I think that is a separate issue based on the stack trace - it sounds like the palette file is perhaps corrupted? Could you attach the palette.txt from your settings directory (it should be something like ~/.config/Pinta/palette.txt, but might be elsewhere if you're using flatpak or snap, e.g. https://unix.stackexchange.com/a/697214)
You should be able to delete that file to resolve the issue, but it would be helpful to know what it contains.

palette.txt

[mikeloeven]

doesn't seem to be the issue deleting that did not resolve

[cameronwhite]

Thanks, yeah using that palette file also doesn't trigger the crash for me.
Which Pinta version and installation method (e.g. flatpak / snap / distro package) are you using?
