Bug Description

With the latest git 2.4 branch, I get a segfault on start after an error message js:warning [Controller] ERROR! new Deck() called without specifying any deck numbers.

If I disconnect the Allen and Heath Xone K1, there is no segfault. If I remove ~/.mixxx, the error and segfault occurs as soon as I enable the Xone K1 in Mixxx's preferences. If I compile and run the 2.3 branch there is no segfault.

rah@acanthus:~$ gdb $(which mixxx)
