All I know for certain, is that I'm using Gnome 2.6, and I don't have any problems with any of my Gnome or GTK+ applications in regards to the clipboard buffers. Yet, when I used applications not based on a particular toolkit or set of libraries this wasn't the case.
Mouse based paste works fine with all applications, without exception. However, I have noticed that some applications don't seem to use the 2 X clipboard buffers in the same way. So it seems that using applications based on the same libraries and toolkit work better together. It also seems to me that when you use a Gnome environment, all keyboard shortcuts are handled by a single source, not by the application, which is how keyboard shortcuts in X used to be handled; at least from what I recall. Is this a possible source of problems as well?
Other than simply getting used to the way unix handles it's clipboard, I've found that using programs compiled from similar libraries does away with this issue.
I use Gnome 2.6 currently, and using Ctrl-C Ctrl-V for copy and paste works in all of the applications I use. Although I do revert back to the double click, and a middle click a lot.
I can only assume that using KDE is similar as long as you stick with KDE or QT apps.
The problem is probably more prominent when using different applications that rely on different library sets. If you're using Gnome as your desktop, and Konq as your browser, ya, you might have an issue. If you use Gnome, and epiphany; you probably won't see this problem.

That's my two cents.
