Hmm, how very peculiar... Well, I get a seg fault every time now with 
that file...

Machine is gentoo, with current packages.  Kernel is 2.6.5-mm (and 
previously it was 2.6.4-mm2 ish - I updated just to see if there was a 
kernel issue).  Machine is a P4 2.8.  I just recompiled glibc with nptl 
to see if that helps, and now it segfaults more frequently, previously 
it would sometimes just die with no segfault message...

Actually I don't get any segfault when it plays back in the preview 
window, which is peculiar.  I wonder if it is specific to the output 
layer in use?  Are you using the Xvmc stuff by any chance?

Actually, the only other thing I haven't thought about is I have the 
alsa stuff compiled in.  It's not in use, so very unlikely to be an 
issue.  Also the app is compiled with debug settings.

Hmm, can gdb do a line by line output trace to a file so that I can at 
least see the last few lines that were executed?
