Hound Hotkey for collecting souls causing strange glitches

I've found out recently in my conquest game that collecting souls by using the hotkey has a strange glitch. If I'm attacking a group of entities (draugr in this instance) and there are souls on the floor but still enemies around, and I use the hotkey (Q), then the game freezes up for a couple moments before returning to normal. This has resulted in a couple situations where the game has fully crashed, or a more odd circumstance I've had over recent months with the game where the sound engine dies for whatever track is currently playing, but alt-tabbing seems to fix that so it's really weird.
