[mythtv] Backtrace: possible bug in dvbsignal monitor

Indeed...  The annoying thing is that it was almost completely stable 
before, (except for the recurring segfault on the occasional program 
preview.)

I may be wrong that it was due to the dvbsignal monitor of course.  
However, the backend is dying quite easily and possibly for multiple 
reasons.  I think I have seen it loose signal suddenly for example and 
lock up.

More annoying though is that before when the backend died, the frontend 
used to popup a box to that effect and continue happily.  Now it pops up 
the box, but then pretty much hangs, the gui goes away, but it doesn't 
actually terminate the process so even my daemontools monitor doesn't 
know to restart it...

Needless to say it's killing usability that I need to keep pulling out a 
keyboard every few hours and start killing processes.  However, I like 
some of the new features in the new DVB code so I am prepared to 
persevere and track these down, but I could certainly do with a bit of 
help where possible in interpreting these backtraces.  For example there 
are a couple I posted recently that perhaps you might have a bit of an 
idea about (perhaps)

Thanks for looking
