Thanks for the report! Unfortunately the valgrind report doesn't give too much
clues (except that this might be a stack overflow). Could you try and see if
this is reproducable with the latest git? You don't necessarily need to install
it, just compile with "./bootstrap-configure && make" and run the compiled
bluetoothd directly from the tree. Also, if you still don't manage to make
valgrind give you something sensible you could also try with gdb to see if it
works better in producing backtrace.
