--- Comment #3 from Wegwerf <wegwerf-1-...@gmx.de> --- Roland, a few things I notice: 1. MLT is outdated, you should upgrade to MLT 6.0.x or 6.2.x if possible. The version gap looks larger than it actually is, but there have been some important bug fixes in MLT with respect to Kdenlive. So if possible, please upgrade MLT. 2. 15.12.3 isn't supported anymore, but you mentioned 16.04.1, so this is recent. 3. The stack trace doesn't seem to make much sense to me at the moment, I'll try to explain why. What is curious is that you may see a crash in pthread_cond_wait() ... is this actually the thread that crashed or is this just the stack trace of one of the multiple Kdenlive threads? What crash did you actually see, a segmentation fault, bus error, or ... ? I've seen "crashes" mostly in pthread_cond_wait() when the crash actually was in a different thread. Of course, I may be on the wrong track here, so that's why I'm asking. In case you didn't already do it this way: can you please run gdb src/kdenlive from your kdenlive build folder. When kdenlive crashes, is the "bt" command giving the same back trace? -- You are receiving this mail because: You are watching all bug changes.
