 I'm not sure of the trigger for the crash, it seems to happen randomly,
 but it does not occur when running under gdb. Attaching backtrace from a
 core dump.  Running trunk rev 26497
 The only thing I see in the logs are:
 *** glibc detected *** /usr/local/bin/mythbackend: corrupted double-linked
 list: 0xa5e19e10 ***

 Followed by the memory map, please let me know if that would be useful to
 attach.  I'm also seeing previewgen segfaulting as well.  It is possible
 that this is just an error on my machine but if so I've been unable to
 locate the cause.
