Created attachment 93713 [details] Backtrace Hi J-B, I was editing for a while when a segfault occurred. I don't know exactly what caused it. I believe it was while seeking a track with 1500% speed. Backtrace is attached Version 15.07.0 (rev. v15.04.0-439-g0d73372) KDE Frameworks 5.12.0
Paul, as there have been fixes and chances to the speed effect some time ago, can you please try with a stable Kdenlive 16.04.2 to see whether your problem has been fixed or not? Please make sure that you upgrade MLT to at least 6.2.0 too. If the big is fixed then I would like to ask you to close this report as RESOLVED. Thank you very much for your cooperation!
Jep, it's fixed. Cheers!
