Could you upload a short example MTS file? I've got some too, cannot reproduce, but perhaps they're h.264. ffmpeg -i doesn't know (Unable to find a suitable output format for 'Borretsch-00016.MTS').

I said M2T file, not MTS or M2TS. M2T is NOT the same as the AVCHD mts/m2ts. M2T is HDV, mpeg2. M2TS/MTS are AVCHD, mpeg4.

Ah, nice to know. Thanks.

Reproducing with a new project:
* Add both clips to project content
* Add both clips to timeline
* Click «Clean up» in the History (first entry). Multiple undo (Ctrl+Z) won't crash kdenlive here.

Seems like a kdenlive problem, not MLT.

Cannot reproduce when running with valgrind :(

No, you have to actually DO some video editing before you can reproduce it. Add a few plugins, remove them. Add some others. Then cut the clips, split the A+V, add some transitions. Overall, have about 20-25 items in your history. THEN, click on an item in the History, about 6-7 levels above the last one. It crashes here.

No, if you only follow the steps I noted above then kdenlive crashes here. I tried to get some more information about the crash by running kdenlive in valgrind but there it wasn't reproducable. I wonder whether it prevents kdenlive from crashing, also tried to split audio/video now and still no crash. Output however:

Sorry, without an updated ubuntu binary, I can't test.

No, I refuse to compile from source, sorry. After years with Gentoo, Slackware and Arch, I am well-situated in a dev-environment-less Ubuntu installation, and I refuse to build anything from source. If it doesn't exist as a binary, it doesn't exist for me. It's a matter of principle, not a lack of skill.
