true but it still needs massaging for function names and other symbols -
juerg mentioned that libvala could do this so it should be easy to
create a vdb app that wraps gdb and mods the output. That way backtraces
could show the vala methods...

IIRC anjunta spawns gdb for debugging via stdin/stdout so it we would be
nice to have the option to replace it with vdb and get the same
functionality in anjunta when using vala
