SUMMARY
Every time I open a video in Image Editor, digikam crashes shortly after. /tmp is flooded with an ImageMagick *.pam file and due to the crash it is not destroyed. The file is several GB large. This results in crashes of further KDE programs. I need to manually delete the *.pam file to stop further crashes.

Please note that I'm not sure if this bug is correctly assigned to Image Editor component or if this is related to another component.

STEPS TO REPRODUCE
1. Open several images in Image Editor including video file
2. Skip to video file 
3. digikam crashes
4. /tmp runs out of disk space
5. Further programs crash

OBSERVED RESULT
Crash

EXPECTED RESULT
Open video

SOFTWARE/OS VERSIONS
Application: digikam (6.1.0)
Qt Version: 5.12.4
Frameworks Version: 5.59.0
Operating System: Linux 5.1.11-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

ADDITIONAL INFORMATION
- No backtrace. Presumably because /tmp runs out of space.
- If only the video is selected to be opened Image Editor, the standard video program starts.
- As workaround I filter out videos before using the Image Editor.
