[Htmlvalidator-help] HTML Validator error in Kanotix (Linux)

[Ron <fef...@sb...>]

Using Kanotix (Debian SID, somewhat based on Knoppix) The HTML Validator 
extention was working fine until recently. After checking Marc's 
CyberHome page, I got the following:

rp@knx:~/.mozilla/firefox/evc3to3e.default/extensions/{3b56bcc7-54e5-44a2-9b44-66c3ef58c13e}/components$

       /lib/ld-linux.so.2 (0x80000000)

I'm not sure how to proceed, any ideas?

Thanks,
Ron
