[mythtv] [0.25] SIGSEGV when EIT updating DB and channel change (sometimes empty file)

I have a reproducible problem and tried several 0.25-pre versions since the beginning of march. On a channel change for a recording
and a running (or maybe just ending) EIT update to the DB I get a SIGSEGV, almost every second day. Twice I saw empty files created
prior the crash of mythbackend.
Since I have these errors, I only activated one card, and allowing only one recording per card.
This crash happened after midnight, so maybe a new day of EIT data was received resulting in the crash.

Thanks for having a look at the debug logs. Please inform me for other settings/tests. 
Cheers Angela
