[mythtv] Seg fault when pressing "o" on a channel with no epg-data

[markus scholz]

Hi all,

when pressing "o" while watching TV to bring up the mini-epg on a channel with 
no epg-data in database I get a segfault. The same is when pressing "o" in a 
channel with epg data and then scrolling through the channels to a channel 
without epg-data:
