Returning B_OK from DeviceAdded() callback, causing a SIGABRT

[codewrangler]

I get (3) DeviceAdded notifications (of Types 0,9,9), which I assume are the USB 'devices' already attached to the system (VMWare Fusion 6.x). After returning B_OK, from the last callback (same for all 3), I get a SIGABRT (according to gdb).

Here is the backtrace:

It'd be helpful to be able to see the code in question, as the backtrace hints at mem corruption, such as a double delete.
