Indeed, there's more to library compatibility than symbols being present.  
Those symbols still have to act in compatible ways.  We will try to make Psi 
0.12 compatible with Qt 4.2-4.4, but unfortunately Psi 0.11 is broken with 
4.4 and there's nothing we can do about it. :(

It would be great if Trolltech could release a 4.4.1 with restored 
compatibility.
