Comment 2 for bug 981193

I have determined some interaction with easystroke, a gesture recognition program is to blame here, not Firefox or ATI exactly. The program easystoke was used to map a side button on my mouse to Super+A, which activates the "Present Windows" effect in KDE/kwin.

Scrolling in Konqueor and hitting the gesture button on the mouse. Crash. It's not just Firefox nor Mozilla. (Thunderbird also crashed in this regard earlier).
Scrolling in the Desktop (cube effect) and hitting the gesture button on the mouse. Crash. It's not a Web page nor plugin.
Scrolling in the above scenarios and hitting Super+A on the keyboard itself. No crash. It's not "Present Windows" nor kwin in this regard.
Scrolling in the above scenarios and hitting the same button on the mouse without easystroke. No crash. Its not the mouse input in that regard.

So, what is the remapping of a mouse button to Super+A and scrolling at the same time in easystroke doing to Xorg or FGLRX?
