[mythtv] 0.18 Hang During Manual Delete

[thor]

 Noticing the frontend can just hang in the Delete Recording popup dialog 
(when I select yes). Not immediately clear to me what the problem is, thus 
the attached backtrace.

 This backtrace is from a remote frontend. Happens from delete dialog either 
in "Watch Recordings" or "Delete Recordings" (this one is from Delete 
Recordings). Quite reproduceable, in case that's required.
