Gilles,

I did what you suggested, uninstalled libmarblewidget, made sure that digiKam
compiled without it, then recompiled and ran the software. Unfortunately, it
crashes right away. Here's the relevant backtrace, again pointing to libpgf:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x13b6b000

I can do valgrind if you want me to... Let me know.

Thanks,
