Not so much video encoding, but /certainly/ encrypted filesystems should 
be /all/ screwed up if it's the memory going, and as I mentioned (quoted 
below), lossless compression such as bzip2, as long as it's checksummed, 
should be showing it too.

Yeah, thread-races could be it.  It could also be the filesystem, but if 
you're running it on encrypted, then no, shouldn't be, unless it's /just/ 
the filesystem, on top of the encryption.

But thread-races would seem to be the likely culprit.

I don't know if you've tried it or are in a situation where you /can/ try 
it or not, but one alternative is K. Haley's pan git repo.  That /does/ 
mean compiling from source, but unlike gtk/gnome/charles-kerr's upstream, 
at least it has current activity, patches applied for several things, 
etc.  If you're where you can, trying it would be a good idea.  Tho I 
don't know of any changes at least as posted here that could affect your 
problem, it's worth trying out, anyway.  Here's the git protocol URL:
