Bug ID: 467763
Summary: Kdenlive crashes when switching to projects in a
certain order
Classification: Applications
Product: kdenlive
Version: 22.12.3
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: fritz.seiff...@protonmail.com
Target Milestone: ---
Application: kdenlive (21.12.3)
Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.14.21-150400.24.49-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.4"
DrKonqi: 5.24.4 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
I attempted to switch projects from one that I currently had open (dubbed
"Project A") to another one (dubbed "Project B"). There was only one opened
instance of Kdenlive. It appeared as if Project B loaded successfully (the
loading bar filled to 100% and the small loading sub-window disappeared, the
clips and the timeline assembled etc), but about 1-2 seconds after this
Kdenlive crashed.
I did the same thing twice again (first Project A, then Project B) and Kdenlive
crashed in both instances. I tried the inverse, first switching to Project B
(from an empty instance) and then switching to Project A, this worked fine and
Kdenlive did not crash. I then proceeded to switching to Project B again, at
which point Kdenlive crashed just as it had before. This last step (B->A->B) I
repeated, with the same result.
Whenever I write "switch" what I mean is going to "File" -> "Recent Projects"
and then selecting the project in question.
The crash can be reproduced every time.
-- Backtrace:
