I'm using Sublime Text 2.0.1 on Ubuntu 12.04 and when I tried to save a file that I have read permissions to, but not write (since I didn't own it in my case), Sublime Text just completely froze up and I had to kill it and reopen. I went through this cycle of killing and reopening several times until I realized I wasn't the owner. After changing the owner to myself it worked fine. There was no notice or anything, just freezing. Repeatable 100% of the time for me.
