I've get a Segmentation fault in mytv-setup while scanning channel on a
The stack trace is :
Program received signal SIGSEGV, Segmentation fault.

Looking in the debuger, it seems that stream_data is NULL.
I put a breakpoint in void
DTVSignalMonitor::SetStreamData(MPEGStreamData *data), but functions
seems to neither be called.
The only reference I found on this function is in tv_rec.cpp, but I'm
not sure if I should look there as I'm in mythtv_setup.
Does the stream_data should be setup when we do a channel scan ? or does
we just need to add a few if (stream_data!=NULL) to correct this ?
