You'll want to set a breakpoint at the place where it's issuing the 
"Unrecoverable error" message.

http://sourceware.org/gdb/current/onlinedocs/gdb/Set-Breaks.html#Set-Breaks

easiest way is to add:

break mythfrontend/main.cpp:123

to your gdbcommands.txt file (right after the "break qFatal" line would 
be a good place).  You can get the actual file name and line number of 
the log message directly from the log output.  Note that the filename 
(when specified as a "relative" file name, as above) will match any file 
with the same trailing components--so, I didn't need to say 
"programs/mythfrontend/main.cpp" because "mythfrontend/main.cpp" is 
unique enough, and if I just said, "main.cpp", it would match main.cpp, 
regardless of application I run).
