Segfault during playback of video files produce by Canon cameras

Description
Attempting to playback any video files produced by either of two Canon digital cameras I have, produces a segfault after the first frame is displayed within MythVideo?. The cameras produce both produce an avi file, one is 320x240 (PowerShot? SD100) the other is 640x480 (PowerShot? SD700 IS).
I am able to succesfully play back the files in ffplay, and various other media players on OS X and Windows. However, both files also crashed mplayer. I also know, that within the older versions of mythgallery, these files appeared to play back succesfully (only tried once a while ago - never attempted within mythvideo).
These segfaults happened in .22-fixes, and I was hoping that maybe they had been resolved with more recent ffmpeg merge within .23-fixes, but I get the exact same results.
I am attaching 2 backtraces and 2 logs, 1 for each file from each camera (Just in case there's any difference). I will also try to attach videos, since they are <5MB each (~2 seconds). These files were created so I could share them for testing, but none of the videos from these cameras in my library will play within Myth.
Thanks!

For completeness - here's the other video: http://filebin.ca/jrrfbj/MVI_0613.AVI
MVI_1141.AVI goes with gdb.txt and mythvideosegf.log MVI_0613.AVI goes with gdb.a.txt and mythvideosegf.a.log
Sorry for the multiple replies...
I'll wait to provide any more info until more is requested.

Janne - Tested again with r24265 from the 0.23-fixes branch and I'm still seeing a segfault, as before the patches, while attempting playback of these files. Please let me know if there's any additional information you would like after the latest test.

Just wanted to report back and that these videos no longer cause a segfault, and in addition play back just fine in 0.24. I'm guessing that the ffmpeg sync may have helped fix it. This ticket can be closed as fixed now.
Thanks!
