Bug 440436

Application: kdenlive (21.04.3)
 (Compiled from sources)
Qt Version: 5.15.3 (KDE Qt5 Patch Collection)
Frameworks Version: 5.84.0
Operating System: Linux 5.12.0-pf4 x86_64
Windowing System: X11
Drkonqi Version: 5.22.4
Distribution: "Gentoo Base System release 2.7"

-- Information about the crash:
I tried to create a project with default options.

The crash can be reproduced every time. Removing ~/.config/kdenlive*, ~/.cache/kdenlive and ~/.local/share/kdenlive didn't help.

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Aborted
