I seem to be having problems with the latest dbus code.
Here is a backtrace. This is happening at startup.
Program received signal SIGSEGV, Segmentation fault.

However, while looking at that code I found a few memory leaks and as part of fixing those I rewrote the code that seemed to be causing your problem and I think it's working better now. -David
