I can confirm this is related to the Dawnguard DLC. When attempting to exit a game with Dawnguard loaded, it doesn't exit and had to in fact reboot my machine. When doing it with Dawnguard disabled it will quit fine.
I second that. Same issue here. Wine 1.9.8 staging with latest/last skyrim update.
A simple web search revealed that this in an issue with those running the game on windows / without WINE as well. Possibly not a wine bug. see here:
