No wonder. I verified the issue exists still by doing this:
$ apt-get source xserver-common
$ zgrep -A2 -B2 650539 xorg-xserver_1.9.0-0ubuntu7.3.diff.gz
+  * debian/patches/207_Xext_panoramiXprocs_fix_typo.patch:
+    - This prevents Qt applications from crashing when using
+      Xinerama multi-head with drivers such as nvidia (LP: #650539).

So it is reported to be fixed in the change log.


$ grep -A4 "pDst == screenInfo" xorg-xserver-1.9.0/Xext/panoramiXprocs.c
    if((pDst == screenInfo.screens[0]->root) ||
       (pWin->drawable.id == screenInfo.screens[0]->screensaver.wid))
    {
        rep.dstX += screenInfo.screens[0]->x;
        rep.dstY += screenInfo.screens[0]->y;

So if compared to the original patch (https://launchpad.net/~jared-
bunting/+archive/xorg-xserver-650539), it is not fixed, only falsely
reported to be fixed.

I'd really liked to see this fix included soon and before next Ubuntu is
released. Althought I'm sure the history still continues to repeat
itself and this will not get fixed before Ubuntu 11.04. Then the Ubuntu
11.04 version will break the multimonitor setup of Xorg (or something
related) again and the fixing takes again more than releasing even next
Ubuntu 11.10 and so on. That's the neverending cycle that have been past
i-cannot-even-remember-how-many Ubuntus. I guess it's just so rare to
use multimonitor setup that they don't test it before release.
