From my limited knowledge of such things, this looks to be a problem in the
compilation of the stdc++ libraries. I am using debian unstable. Can anybody
confirm my theory? Any suggestions?
The backend runs normally until I try to change input source with 'c' while
watching LiveTV, at which point I get a Floating point exception. Specifically
I am switching from a Nova-t card, to a PVR-250 Tuner.
Program received signal SIGFPE, Arithmetic exception.

Let me know if I can provide more info. The full 'bt' of all threads for example.
