I'm able to reproduce this crash on the current head.
My impression after running it through the debugger is that -release is
called on the pixmap after it has been deallocated earlier in pbm_load.
I have created a patch that sets the pixmap to NO_PIXMAP in case
pbm_load runs into an error.
In the long run the better solution is probably to look over the NS
memory management so that it works properly.
