Apparently this part of the code has changed considerably after the 0.23
release, so this issue is unlikely to be addressed in 0.23, and so would
need to be reproduced on 0.24 (which is still under heavy development).
If you have the ability to try this on a test partition (or system), it
would be greatly appreciated.

mythfrontend crashes when EPG changes (same as #613547)

Status in “mythtv” package in Ubuntu: Triaged

Bug description:
Binary package hint: mythtv

This only happens in YLE (Finnish national broadcasting company) channels but on them without an exception. Every time the EPG data changes to mark the beginning of the next program, MythTV frontend crashes without even an error message, both when watching live TV or a recorded program. The bug has been previously reported by another person as #613547.
