Comment (by Aidan Thornton <makomk at lycos.co.uk>):

 This isn't actually a race condition, which is why it happens so reliably.
 Basically, write_section_data calls tss->section_cb - which is pat_cb -
 and this (incorrectly?) deletes and recreates the PAT filter, as Janne
 said. However, the variable tss in write_section_data still points to the
 now-freed filter, and when it tries to do some more stuff with it,
 mythfrontend segfaults. (All this happens within mpegts.c)
