Yeah, this sounds all to familiar to me! I have one contact in particular who always seems to trigger these bugs when he sends me files. I'll have to ask him, "What are you sending," seeing as I'm not able to view the file name.
Auto-accept also gets really annoying at times. In half the cases it simply doesn't accept the file being sent. Are you by any chance experiencing this as well? I wonder if these two problems are related...
