- Category set to EPG

- Assignee set to Adam Sutton
- Found in version changed from lastestmaster: 5159505c31b4db29f2ef3d52e627eeb7d276b875 to 5159505c31b4db29f2ef3d52e627eeb7d276b875
Good spot, what a shit bit of code that is. However I don't think this explains the more general issue. I've been trying to track down the xmltv crash for a week or so. But struggling to find the time at the moment. Plus reproducing it is proving difficult.
Adam
PS I'll merge the patch as soon as I can.

Ok, patch applied.
This does indeed explain both of these reports and it was my error regarding the other crash (which is still an issue).
Thanks
