Description
Frontend occationally crashes when playback is started. See attached backtrace which suggest that this might be MythSystem? related. Didn't have time to test/report this on ticket #9421.
As shown on version output, local version is "dirty" but those modifications should have nothing to do with this.

Attached the requested log (not from the same crash as the backtrace). Started frontend, started playback of recording twice and the second one crashed.

OK, give this patch a try if you could, please. You seem to do quite well at finding the little tiny edge cases that I just can't get to fail here. :)

Patch seems to fix the issue, no crashes with it :)

Try to keep from another apparent race condition
Not quite sure why the QMap is going crazy, but let's try reading the AutoCleanup? flag before unlocking so we can mitigate the race some. Also, in both myth_system() and in the signal handler, use deleteLater() so we don't try to double-delete, as that will just cause other messes.
Fixes #9602
