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.

New information: A friend of mine who’s using VDR told me this phenomenon has been discussed in VDR’s forum some time ago; I couldn’t find it however. It seems the originator is not EPG in itself. At the beginning of each new program, YLE assigns language codes for all the audio and video channels. (Many programs have both Finnish and Swedish audio and subtitles, and additionally YLE uses “Dutch” for the hearing-impaired subtitles and for the visually-impaired audio channel.) This might be against the DVB spec or not, I don’t know.
