[mythtv] Segmentation error in frontend with on air DVB-EPG

Fri May 6 12:43:49 UTC 2005

When i go into the program management screen mythtv gives a sigseg.
I have upgraded to QT 3.3.4, and tested it on mythtv v 0.18 & mythtv CVS @ 
6.5.2005 (DD/MM/YYYY).
It worked before i checked EPG to Use on air guide (in the channel editor in 
mythtv-setup) on a DVB-S channel (VIVA on astra).
Contact me if more information is needed.

Here is the GDB backtrace of the frontend:
