Comment 1 Vincent PINON 2015-12-28 21:01:22 UTC

Sorry for late reply,
which Ubuntu/Kdenlive version are you testing?
the crash comes from SDL library, where you playing a special audio file / using some audio scope?

Comment 2 Wegwerf 2016-07-31 09:10:11 UTC

Thomas, can you please test using the recent stable Kdenlive 16.04.2 version, with MLT 6.2.0+ at least? Does the bug still persists? If not, I would like to ask you to be so kind as to close this bug report. Thank you very much for your cooperation!
