I've also seen a rather large increase in the number of segfaults from
mythcommflag after upgrading to 0.25.  I haven't had time to do any further
debug yet, but all of my segfaults are happening in the libavcodec code
thus far.

mythcommflag[14031]: segfault at ad0df000 ip b65d23bf sp ac7846ec error 4
in libmythavcodec.so.52.113.1[b6174000+59a000]
mythcommflag[15577]: segfault at ad0df000 ip b66253bf sp ac28491c error 4
