I probably ran into the same issue (or closely related). I post a valgrind output if this can help:

Unfortunately, this still seems to be crashing. Additionnal info : - The crash occurs on loading (not saving as original bug report) - The value of the p->description (before the faulty free) is "HDV 1440x1080i 25 fps" Tell me if you need anything else. Git commit 36b808f60b67cee4c182d77bb774096278a649e3 by Jean-Baptiste Mardelle. Committed on 03/09/2016 at 14:41. Pushed by mardelle into branch 'Applications/16.08'. Fix crash on audiospectrum display M +2 -1 src/audiospectrum/audiographspectrum.cpp http://commits.kde.org/kdenlive/36b808f60b67cee4c182d77bb774096278a649e3 @Jean-Baptiste: the last referenced commit is probably CCd to the wrong bug More info about the bug of this thread : the bug triggers only 50% of the time, I don't know why. Hi, the backtrace you attached is related to another bug report (crash in audiospectrum). It should be fixed now. About the profile->description crash, not sure it is related to original crash report. Can you describe precisely what you do before the crash ? Are you opening a project file ? If yes, what is your default Kdenlive project format and what is the opened project format ? Very sorry about the backtrace : I actually accidentally included both the backtrace for the audiospectrum and this one (didn't know that gdb was appending and not replacing the log file accross sessions). You can look-up "raise()" to confirm that there is also the backtrace related to this bug. I'm not 100% sure either that this is the same crash, but the backtrace is very similar. The relevant part of the original one is : Thread 36 (Thread 0x7fff537fd700 (LWP 8377)): #0 0x00007fffefdbe04f in raise () from /usr/lib/libc.so.6 #1 0x00007fffefdbf47a in abort () from /usr/lib/libc.so.6 #2 0x00007fffefdfbc50 in __libc_message () from /usr/lib/libc.so.6 #3 0x00007fffefe01fe6 in malloc_printerr () from /usr/lib/libc.so.6 #4 0x00007fffefe027de in _int_free () from /usr/lib/libc.so.6 #5 0x00007fffb15bf8da in ??

As for triggering the crash: I start the program, open the project. Then I get a dialog regarding missing clips, I choose "Use placeholders for missing clips" and then I have the "loading playlist" dialog, and it crashes during that. As for the format : I'm not sure where to read that, but the following line gets logged when opening the project: Opening a document with version 0.95 / 0.95 Does this help ? Could you attach the crashing project file here or mail it to me? Git commit 4cee6a07366963542253afe761bf8b525da561e0 by Jean-Baptiste Mardelle. Committed on 04/09/2016 at 09:41.

What's the outcome? unfortunately at the moment i am not able to test this since the files are not with me :/ It happened again today. I'm a little bit behind master (6a6ad3742f3e28d82162f83ffdc1be94fda63f1e) but apparently no relevant commit has been pushed since then. I'll attach a new backtrace in case that helps.
