Javascript bug with Typetool

["Pyroman[FO]" <pyroman ninjapanda org>]

I am using the latest (R8.0) Typetool (vietdev.sourceforge.net) RTE as a 
plugin for PostNuke.  This uses javascript and the mozilla RTE interface 
to create a word processor like editor for HTML in a text box.  This 
works fine in Mozilla 1.6.  However both Mozilla Firebird 0.7 and 
Epiphany 1.0.7 choke on it, with different errors.  The Epiphany error 
is very strange and I was hoping somebody here would recognize it.

"An error occurred while loading or saving configuration information for 
Ephy. Some of your configuration settings may not work properly."
with a details button, which gives
"Bad key or directory name:
 "/desktop/gnome/url-handlers//command": Can't have two slashes (/) in 
a row"

Does anyone recognize this?  Like I said it works in Mozilla but not 
Firebird or Epiphany.  It seems to be a mozembed problem.
