[Libreoffice] gdb: catching exceptions...

since my smoketest failed again today, i've distracted myself a bit with 
GDB Python scripting, the result of which is a command that can break 
when an exception is thrown, but only if a certain function (which is 
given as parameter) is on the stack.

seems to work, but it is quite slow: finding the smoketest exception in 
SfxBaseModel::getTitle takes GDB 4 minutes of CPU time.

now probably somebody will tell me that i'm too stupid to RTFM and there 
is a much simpler way to do this :)

regards,
 michael
