Comment 6 for bug 1812426

Florian, are you still having the issue? Could you post what version of Fedora you are on?

Could you say when the original file was made?

In Fedora 29, my current flatpak version doesn't crash.

The version says 0.92.4 5da689c313, 2019-01-14. I'm very confused but I downgraded to an earlier version of Inkscape in flatpak (with a date around 2019-01-18) and the version info in the About is exactly the same. Anyway, I did replicate your errors there, but not in the latest flatpak.
