Wavemon segementation fault

I have Knoppix installed on the harddrive of my IBM Thinkpad 390E laptop. Everything runs quite nicely, including my wireless NIC except for one tiny problem.

Every time I try to invoke Wavemon I only get a Segmentation Fault.

I've fiddled with all of the settings I can think of (I'm using this installation to learn how to configure wireless networks in Linux) with no change in Wavemon results.

The strangest thing is that Wavemon seems to work fine when I'm running Knoppix from a CD (or even when I boot from CD to a HDD image).

Hardware is an IBM 390E laptop and a NetGear 511 wireless-g card.

Has anyone experienced/debugged this problem?

I found the problem myself, it seems that Wavemon definately wants to see something in the COLORTERM env variable.

Correction, it was the terminal size.
Wavemon wants 80x24

Perhaps some error message would be usefull.
