Track.003 has some weird frame number of few millions, which does not seem to be correct and most likely caused by error in some tool. So in order to fix the crash we need to figure out which tool produced such a bad track.

And for that we need your input about how to reproduce such a corrupted file form non-corrupted state.

my last backup file is track3.blend, wich solves without problems
I worked with my build of (unmodified) master of 28.1.2015 i think
with this file i used the original video file: 00019.MTS(on pasteall because of file-size limit, delete extention ".blend")
wich causes some trouble, because of the compression. so, in the last session (now with RC2) I converted the video to a png sequence, and i decided to track the whole video (not only until frame 126). Then I can't solve the motion, I have no idea why.
"Track.003" seems to have no keyframes (displayed) in the timeline and shoud be disabled the whole time... then it schoud not have an impact in the solve. I dont want to use the track anyway, because it was bad tracked.

Have I have to upload the png seqence to? (about 230MB would take ages, only exported with default settings)

What do you mean with weird frame number?

Track.003 does have two markers: first one is at frame 0 which is muted, second one is at frame 109147000 which is keyframed and non-muted. Such frame number should not happened i guess.

For reproducing the issue it's not enough to have files, it's also crucial to know exact steps which makes the track corrupted.

Then i have no idea... I know only that Blender crashed a few times during prfetching the video file, when the current frame ist not 0 or 1. (which is caused by a not activated swap, i think) I used the autosaved files a few times. it is maybe saving error, but I don't think that it is reproducable.
Maybe it can be fixed if the code ignores keyframes higher then 300000, wich the timeline can't display, but thats not ideal. I do some testing but i don't think that i can reproduce.

By the way, a backward prfetching with a compressed video file (wich appears when the current frame is in the middle of the video and the prefetch reaches the end) is not ideal, high cpu and compression issues. (better prefetch only forward)
