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

 I encountered a similar crash on one particular DVB-T recording (the top
 part of the backtrace is almost exactly the same) - this was when watching
 the recording, and always occured at the same point in the recording. I
 was using SVN trunk r10088, and I suppose I'll attach my backtrace as
 well.

 The direct cause of my crash seems to be the line
 "memmove(tss->section_buf, tss->section_buf+tss->section_h_size, left);"
 in mpegts.c:write_section_data - tss->section_buf is NULL at the time of
 the crash:

 {{{
 (gdb) print *tss
 $1 = {section_index = 183, section_h_size = 16, section_buf = 0x0,
 check_crc = -1, end_of_section_reached = 0,
   section_cb = 0xb744079a <pat_cb>, opaque = 0x28}
 }}}
