With a new user who has no Vorta config 2. Open Vorta 3. Do nothing 4. Quit from tray icon 5. Exit code 139 (SIGEGV) Here is the backtrace:

Sandro, can you tell if this backtrace indicates that Debian's PyQt and/or QtWidgets might have a problem? "kernel/qwidget.cpp: No such file or directory" Cheers, Nicholas
