Hi Petteri,

thanks for running my test case. I'm using the standard Debian etch
distribution on my NSLU2 and also rrdtool from apt, since I don't have a
development environment installed.

I think I will forward my test case to the maintainer of the rrdtool
package in apt, maybe he can reproduce the error.

Regards, Richard
