Looks like the bug is in CluTk. Worth investigating to see if there's an obvious issue with that location in the scroll-view code.

I am not 100% this fixes the issue (I am amused this hasn't actually caused further issues actually) but it looks like we did some bad math.

Jason, have you found a reliable way to reproduce this? I'd like to target this to karmic. Based on your previous comment it sounds like there could be some corner cases waiting to rear their ugly head with this.

Neil tells me this should be fixed with clutk >= 0.2.8; please reopen if it isn't.
