[mythtv] 0.17 - mythfrontend freezing at end of recordings

HI,
here are the two backtraces for the above video freezing problem
in the first one mythfrontend hangs and needs to be killed
upon pressing a key ("esc") while the video is frozen for a few seconds at the
end of a recording
in the second one the frontend segfaults upon pressing a different key ("9")
while the video is frozen
of course, am i correct in assuming the video shouldn't freeze long enough to
allow keypresses in the first place?
usually it freezes for about 1-6 seconds , sometimes longer (10-30sec) and it
does eventually exit to the menu,
but it's tempting to hit a key and end up awith a hanged frontend
I hope this helps,
please let me know if there is anything else that i can do
to help figure this out
Risto
