gitk error: expected integer but got "Hamano"

I keep running into this error today when using "gitk --all" in my local
git.git clone. It happens everytime when I use the mouse to grab the
thumb button on the scroll bar, and drag it up and down rapidly.

I'm running git 1.5.3.6.862.g3f72.

I'd try to debug myself but my knowledge on tcl/tk is rather limited
(read: zero).

Cheers.

See my mail "Corrupted (?) commit 6e6db85e confusing gitk", which
describes the reason in detail.
