Arch Linux

Description:
Application was installed via Arch Linux prebuild packages (https://www.archlinux.org/packages/community/x86_64/doublecmd-qt5/ [^])

Whenever the Application is quit (either via menu or alt + x) it crashes and
the doublecmd process hangs forever. Even slowing down the logout/shutdown process.

It is reproducable on all 8 of the systems, that I use.

Console output:
