           Summary: Speech Recognition fails with vosk-model-en-us-0.21

Speech Recognition works OK with vosk-model-en-us-daanzu-20200905 - although
the accuracy leaves something to be desired.  I thought I would try with a
bigger 'speech model' to see if that would work better - but when I tried
kdenlive just terminated like a 'Mission Impossible Cassette'.

STEPS TO REPRODUCE
1. Configure kdenlive to use either vosk-model-en-us-daanzu-20200905 or
vosk-model-en-us-0.21
2. Load a video clip with English speech available
3. Set the 'selection bar' as required
4. Project->Subtitles->Speech Recognition

OBSERVED RESULT
If using vosk-model-en-us-daanzu-20200905 a set of subtitles are produced. OK!
If using vosk-model-en-us-0.21 the program terminates without giving any
warning or obvious error message.

EXPECTED RESULT
I would expect either model to produce a set of subtitles.  If there is a
problem, I would expect a message to advise me of the problem/
