I am running IDEA 8.1.3, build #9886 on a Mac (Snow Leopard, 10.6.1). 'git pull' used to work, and now it suddenly doesn't. I get no reaction from the IDE at all - it doesn't lock up, control is returned immediately. So far I have been able to issue all the other git commands. I upgraded to v126.96.36.199 of git, and it still does it. The only thing that has changed around this time is upgrading to Snow Leopard. I've rebooted, reinstalled (IDEA) and run a repair disk permissions, and it doesn't fix it. It doesn't matter what branch I currently have checked out.
Oddly enough, it seems to be restricted to specific projects. I opened another one and it worked fine.
I can't find anything related in the console logging. Are there any internal logs that might hint to what is happening?
