mythfilldatabase crashed with SIGILL in MythContext::ClearSettingsCache()

[Gregor Rosenauer]

Binary package hint: mythtv

crash report via apport. Got a crash from mythfilldatabase on an automatic run, using tv_grab_ch_search
Possibly cause by the fact that Mythtv won't connect the channels found by an automatic scan with the channels found by tv_grab_ch_seach although the channel short names do match, so it should be possible to do automatically...
As I have not yet manually connected / merged the channels, maybe this results in a crash in mythfilldatabase as no channels are found...?

Howdy, and thank you for helping to improve Mythbuntu. The mythtv developers upstream have stopped focusing on 0.21 based reports in preparation for a 0.22 release later this year. Is this issue reproducible on 0.22? If it is, we can try to forward this bug upstream with a stacktrace/backtrace to get the right eyes focused on it.

We have builds of mythtv 0.22 available on a PPA to test. Please follow the directions at http://mythbuntu.org/auto-builds to enable them.

WARNING: If you intend to revert back to 0.21 after testing, you will need to back up your database before upgrading.

    Thanks!
