Segfault when closing mixxx

[Max Linke]

I noticed that mixxx exits with a segfault on debian sid after revision 3345.

here is the back trace for the segfault

#0 0x00007ffff160a702 in libusb_exit () from /lib/x86_64-linux-gnu/libusb-1.0.so.0

the problem does not occur in wheezy. So I'm not sure if the bug is in the debian package, libusb-1.0-0, or if there is a error in mixxx.

thanks -- fixed now

The issue was that hidapi and our new Bulk USB system both used libusb without a private context.
