Bug#369202: Update: not a konqueror bug

[Ulrich Eckhardt <doomster@knuut.de>]

Firstly, I'm seeing the same on a different system, too now. The first system 
was x86 based but I also see it on a PPC based machine here. The hardware is 
completely different (even mouse, keyboard and monitor) with the exception of 
a USB hub. I now unplugged said hub and attached the keyboard directly, and 
couldn't reproduce the bug. I then replugged the hub first and later also 
plugged the keyboard into the hub, and still can't reproduce it. These latter 
attempts BTW also happened on a recent Ubuntu, so it might even be non-Debian 
specific.

Further, and what gave me the hint that it's not konqueror, you can watch this 
bug in action using 'xev'. Before the unplugging/plugging above, I could see 
a series of events where the left shift and control keys were triggered, see 
below the output. As you can see, the time distance between the press and 
release events is at most one (tick? microsecond?), much smaller than what I 
could manually generate.

What I now need is to a) find out when this bug happens (I have an uptime of a 
few days, maybe it requires some value to overflow in the USB subsystem?) and 
b) a way to monitor keyboard input without X (any idea?).

cheers

Uli
