Using Arch Linux 64-bit, Kdenline 16.04.1 I also see this on openSUSE 13.2 with 0.9.10. Also getting this in Arch Linux 64-bit with kdenlive 16.04.1 when applying volume effect to audio track. Sadly the backtrace doesn't contain debugging symbols, so it is not of much use. Please install those and provide a better backtrace.

Please install those and provide a better backtrace. See also > https://techbase.kde.org/Development/Tutorials/Debugging/ > How_to_create_useful_crash_reports I've looked all over on how to install debugging symbols on arch linux, but am coming up empty. The list of required packages is for Ubuntu (or similar) distros, and Arch doesn't have many equivalents (such as kdenlive-dbg). I've looked into compiling it from source, but have had no luck there. If someone more experienced with Arch than I could help me install the debugging symbols, I would love to provide a backtrace. Now with version 16.12 the problem seems gone! Maybe there was some change with the effect categories? Now there is Audio correction - Volume (Keyframable). In comment 2 I reported an immediate crash when applying Volume effect to an audio track. Now it does not happen and I can also preview it. quiwy: could you re-test and hopefully close as resolved worksforme?

Yeah it looks like there is no moe "volume" effect but only "volume keyframable" that still working fine. So I guess it's not a problem anymore :) Ok, let's close! |
After editing video and adding an volume effect kdenlive crashed. Reproducible: Always Steps to Reproduce: 1. Open Kdenlive 2. Add a clip or an audio clip 3. Put an effect on it from "audio" category 3. Play the preview, when cursor reach the clip with effet Actual Results: Kdenlives crashes Expected Results: Continue playing preview [volume @ 0x7fff7bdd23e0] [Eval @ 0x7fffa891d380] Undefined constant or missing '(' in '' [volume @ 0x7fff7bdd23e0] Unable to parse option value "" [volume @ 0x7fff7bdd23e0] [Eval @ 0x7fffa891d380] Undefined constant or missing '(' in '' [volume @ 0x7fff7bdd23e0] Unable to parse option value "" [volume @ 0x7fff7bdd23e0] [Eval @ 0x7fffa891d380] Undefined constant or missing '(' in '' [volume @ 0x7fff7bdd23e0] Unable to parse option value "" [filt @ 0x7fff3a6cf180] [Eval @ 0x7fffa891d9b0] Undefined constant or missing '(' in ''1.0'' [filt @ 0x7fff3a6cf180] Error when evaluating the volume expression ''1.0'' [filter avfilter.volume] Cannot init filter Thread 32 "RenderThread" received signal SIGSEGV, Segmentation fault.
