Notes
(0008129) evorster (reporter) 2012-06-16 18:13	I have been doing some testing. Kdenlive does not segfault with ffmpeg 0.8.12, but does segfault with ffmpeg 0.9.2 Also, I am beginning to suspect that the fault is in MLT. The distro I am using (Sorcerer) detects if and ELF requirement is not met when changing a source version, and automatically rebuilds affected programs. Between versions 0.11.1 and 0.10.4 there was an ELF break with MLT, but not between versions 0.10.4 and 0.8.12. It merely told me that all my clips were invalid until I re-compiled MLT. There was no ELF break between 0.8.12 and 0.9.2, but with 0.9.2 Kdenlive started segfaulting on loading this clip. The clip's size is 60mb, which, if I remember correctly, is outside the limits set for the upload of clips at kdenlive. Any ideas of where to look next? Can I have special permission to upload this clip to see if you guys get the same segfault? Kind regards, -Evert Vorster-

(0008133) evorster (reporter) 2012-06-20 18:14	I got a hold of Dan Dennedy on email, and we sorted this segfault. It was down to my mlt not updating with git. Please close this bug! -Evert-
