NVDA stops working after using Windows Media Player #5467

Hello.
NVDA often stops working after using Windows Media Player 12 on Windows 7.

STR:

1. Open any media file with WMP
2. Tab to any playback control and interact with it
3. Close the player.

After closing the player NVDA starts to give errors on every movement of the focus and completely stops speaking. After this, the only way to continue working is to restart NVDA.
This happens almost always, but sometimes it doesn't. Also, this generally doesn't happen when there was no interaction with the player's controls.

Here's an extract from the log.

ERROR - eventHandler.executeEvent (18:26:08):
error executing event: gainFocus on <NVDAObjects.IAccessible.IAccessible object at 0x05DE6790> with extra args of {}
Traceback (most recent call last):
File "eventHandler.pyc", line 138, in executeEvent

File "appModuleHandler.pyc", line 240, in handleAppSwitch
AttributeError: 'AppModule' object has no attribute '_configProfileTrigger'

I'm using the latest next snapshot of NVDA on Windows 7 x64. I also tried both 32 and 64-bit versions of WMP with same results.
Thanks.
