FWIW I get a very similar error running 6.0.0-1 on Kubuntu 18.04.1:

Basically I was trimming an mp4 file, cropping off the end of it; the "save media" button continues the conversion until it gets to 60% and then hangs forever. In at least one instance the main process had 22 sub-processes.

If I turn off frame accurate processing then the job completes without issue.

I confirm this conversion problem after "save" which blocks around 60% (with DV files)
The problem does not occur if "frame accurate cutting" is not enabled.
This problem may be similar to report #218 (Export freezes at 50%[could not open codec])
Version: 6.0.0 - Flatpack
System: Linux Mint mate 18.3 64bit

I observe the same behavior at 80% with vidCutter 6.0.0 on Linux Mint 19.2 64bit

• Original video file: MP4 v2 [ISO 14496-14]
• I crop a part from the beginning and the end
• I have frame accurate cutting enabled.
• I toggle the audio steam off

If I toggle audio steam on, it works.
If I disable frame accurate cutting, it works.
