Krita segfaults during save when using xmonad (using plasma5 is fine) (17.09 regression) #30807

Issue description

When I use xmonad as window manager Krita segfaults when I try to save a document (gdb output):

Thread 1 "krita" received signal SIGSEGV, Segmentation fault.
0x00007fffef510c49 in QString::indexOf(QString const&, int, Qt::CaseSensitivity) const () from /nix/store/nwvydrhhmfvf5g8ybh135rgpl9xyzvvb-qtbase-5.9.1/lib/libQt5Core.so.5

I suspected that it had something to do with KDE/Qt stuff missing, so I tried using plasma5 as desktop environment and then the problem was not encountered.

Something else worth noting, I can't load autosaves, I get the error message "Unknown file type" and the terminal is filled with this error message:

No file found for ".xml" , even though update-mime-info said it would exist.
Either it was just removed, or the directory doesn't have executable permission... ("/home/me/.local/share/mime", "/home/me/.nix-profile/share/mime", "/run/current-system/sw/share/mime")

Steps to reproduce

  1. nix-env -i krita
  2. Start krita
  3. Create new document
  4. Press "Save" or "Save as" in File menu
  5. Segfault

Technical details

Edit: I just tried this with the exact same config, but on my laptop that I haven't yet updated from 17.03 to 17.09, and I don't encounter the problem there. I'll get with the exact commit.

I'm getting the same error messages with another Qt application I'm trying to package. For me putting kxmlgui in environment.systemPackages solved the problem while adding it to the package's dependencies didn't help.

I'm closing this since it's stale and I haven't used 17.09 in a long while.
