This crash seems to be very similar to what I've seen in previous releases. I have the impression that it happens most often when I select a message in Evolution.
I believe that the crash is happening because there are no checks to make sure that the clipboards are only synchronized when supported formats (text and Unicode text) are being copied to the clipboard.
In other words, if you try to copy an image in X11 we will grab ownership of the Win32 clipboard and advertise that we have text ready to paste on the Win32 clipboard. We will also grab ownership of the PRIMARY and CLIPBOARD selections in X11 when you copy an image in Win32 and we will attempt to request the clipboard data in CF_TEXT or CF_UNICODETEXT formats when that data is pasted in X11; obviously, this does not work.
I do not believe that there were ever any reals checks to prevent this from happening before... or maybe it just worked out that checks were not needed as a side effect of how the previous system worked.
In any case, I am writing up a list of things that need to be done to ensure that we only synchronize the Win32 and X11 clipboards when supported formats (text and Unicode text) are being advertised on either clipboard. In all other cases we need to keep the Win32 and X11 clipboards independent of each other so that they don't try to transfer unsupported formats between each other.
This will probably be posted as XFree86-xserv-4.3.0-35 later today or in a few days.
Thanks for testing,
