Public bug reported:

I created a dump using mydumper.

Gdb tells me the following:

I am using version 0.9 from checked out from launchpad. If you sense there's a line mismatch it's because I've added a couple of g_message()'s into the code since I'm debugging this and I forgot to locate and remove them. The function calls are there though..
