Crash after sleep

[ris58h]

I get EXC_BAD_INSTRUCTION when laptop wakes up after sleep.

Stack trace:

It seems like it's an issue with MTDeviceRelease(mtDevice); line. When I comment out this line it works fine.

Looks like MTDeviceRelease() sort of happens automatically on system sleep, and an object can't be released twice.

I bet the same error will be thrown if you try running MTDeviceRelease() before MTRegisterContactFrameCallback() and MTDeviceStart().

Maybe interesting?

I've found out that checking that device is running as it's done in OpenMultitouchSupport prevents from a crash after sleep DOESN'T HELP.

UPDATE:
I've checked one more time and the issue is still here. Only not releasing a device works for me as it's done in Touch-Tab.
