There are actually a lot more... I'm sure the developers know the main ones by now.

 

I wonder when we get our first patch!

You forgot the main one:

 

Black screen with music and cursor after loading screen (roedrick's hold, end of Act 2, and other places). 

 

It is a progress stopping bug with no workaround.

Like the ones where things disappear for no reason. Up to and including entire party members.
