How to get rid of text attributes?

[skip at pobox.com]

Thanks for the functions.  I get an error when executing
remove-all-highlighting:

    Wrong type argument: number-char-or-marker-p, help-echo

I tried setting debug-on-error but didn't get a backtrace.  "help-echo"
doesn't exist as a function or variable.  What's a fella to do?

Thx,
