Comment (by cizek at rcn.com):

 I dug through the logs and backtrace and I think it's related to a race
 condition when the DVBSIParser is created.  The base thread and
 SystemInfoThread both use pnum_pid with no synchronization. (This is
 visible in the log file in threads 0xb340ebb0 and 0xacfc4bb0 - for
 threadid info see trac #1344)

 I've attached a patch that creates a mutex lock for this.

 If you need any clarification let me know,
