There is a bug in the Unix sqXWindow.c code that doesn't properly refuse 
anything but XA_STRING clipboard target requests. As a result, Qt programs 
(including all of KDE), which ask for TARGETS (wanting to know about what 
types are supported) get a string response they can't handle, but with the 
type they requested.

There is a comment in the source that actually acknowledges this problem 
("this should REFUSE the selection if the target type isn't XA_STRING") but 
nothing was done. So I fixed it.

The attached patch fixes this problem by refusing clipboard requests that 
aren't asking for XA_STRING.

It also uses a real timestamp for the XSetSelectionOwner rather than 
CurrentTime, since the ICCCM manual says that we shouldn't do that. I don't 
know how much difference that makes.
