I agree with the OP that this is not recommendable behaviour for a library. If you \
can cause a deliberate crash you can also almost always also return an error that \
allows the calling code to handle the situation gracefully (and correct the bug). I \
know it's the annoying part of coding but it's not like DBus isn't a mature and \
well-maintained piece of software where all the easy-out error handling could have \
been made more constructive.

In an ideal world the devs of the calling code would catch all those bugs and the \
resulting crashes but in practice they'll only catch the most obvious ones. The \
remaining ones will all be in the face of users who just happen to play the role of \
fool proofer...

My 2 cents (that aren't up for debate)..

R.
