SUMMARY
After closing krita, a system notification appears saying krita closed unexpectedly, even though closing it was intentional and done cleanly.


STEPS TO REPRODUCE
1. Close Krita, either by shortcut, X button on the window manager, or the Quit option in Krita's file menu.


OBSERVED RESULT
Krita gives this output after being closed:

(process:24790): Gtk-WARNING **: 15:18:42.059: Locale not supported by C library.
        Using the fallback 'C' locale.
Invalid profile :  "/usr/share/color/icc/colord/Crayons.icc" "Crayon Colors"
Invalid profile :  "/usr/share/color/icc/colord/x11-colors.icc" "X11 Colors"
krita.general: convertAndSetBlendMode: Curve conversion is not implemented yet
krita.lib.widgets: The file could not be parsed.
QObject::startTimer: Timers cannot have negative intervals

[1]  + 24790 suspended (signal)  krita

Then, after a minute or so, krita outputs the following:

QSocketNotifier: Invalid socket 20 and type 'Read', disabling...
QSocketNotifier: Invalid socket 21 and type 'Read', disabling...
QSocketNotifier: Invalid socket 22 and type 'Read', disabling...
Unable to start Dr. Konqi
Re-raising signal for core dump handling.

[1]  + 24790 segmentation fault (core dumped)  krita


EXPECTED RESULT
Krita closes cleanly and instantly
