Bug Description
Using a Reloop Digital Jockey 2 Master Edition with Mixxx software, the Mixxx program crashes when I just press one of the play buttons (on the Mixxx GUI) after loading a music. Sometimes it gives Segfault, sometimes gives SIGABORT.
The debug information will contain several "PortMidi: `Buffer overflow'", "QMutex: cv destroy failure", "QMutex: mutex destroy failure" and finally "Segmentation fault" after many "Requested control does not exist" and ControlObject:
(See: http://
I am using Mixxx v1.10.1 installed from the ppa:mixxx/mixxx repository, on my Kubuntu Natty 11.04 64bit.

Motherboard: ASUS Crosshair V Formula
RAM: 8GiB (2x DIMM DDR3 Synchronous 1333MHz)

Controller:

As requested by D.J. Pegasus in the forum, I have created a couple of backtraces (attached). I do not have debug symbols for Mixxx, thus I decided to at least install the Qt symbols (ubuntu package: libqt4-dbg) to provide as much information as possible.
I would be glad to rerun the test if someone would provide the debug symbols for Mixxx.
Attached backtraces: Note that since I could not find a way to attach more than one file, I was forced to concatenate three backtraces in ONE file, separated by few lines full of asterisks '******
1. Backtrace_
2. Backtrace_
3. Backtrace_
Note that in all tests, the way to crash the program is to: 1) Load a music in one or the two sides, and 2) Click a Play button on the GUI.
