Hi Oriol,
Sorry for the delay. I've never seen those MIDI mapping warnings
("Warning: Missing <key> or <type> in MIDI map node: "#comment"")
before, so they might have something to do with this crash.
If you want to find the place where it hangs, I'd first generate a
backtrace and post it here:
http://mixxx.sourceforge.net/wiki/index.php/Backtraces
I can help you pinpoint the spot where it crashes from the backtrace.
There's a nice front-end to gdb that I use for debugging called
"nemiver", and I'd recommend using it if you want to step through the
program to see what happens before it crashes.
Thanks,
Albert
