mythfrontend deadlock if have problems with liveTV

[voyo <voyo@…>]

If mythfrontend have problem (for some reason, doesnt matter now - can be poor DVB signal, or problems with CAM) to tune LiveTV channel it returns to main menu, with message "Error opening jump program file" and then freezes - its not reacting to remotecontrol nor to MythFrontend Network Control. Only I can do is to kill it. Its regression, in older version (can't tell exactly when, for sure in ~0.24) I never had this problem (was crashing too, but was still respondent).
