Matlab problem with web browser

[steak-sandwich]

hey guys,
I installed matlab R2007b on my kubuntu 7.10
I have one problem. When I try to open the "video" in the command window I get this error message (see attached file)
I have already changed the docopt.m file.
when I type in docopt, I get the following:

>> docopt

ans =

mozilla

>>

therefore mozilla is my default browser.
but why do I get the error message?
thanks

Maybe stupid question but do you have mozilla installed? If you want to use firefox as your browser you should change line to firefox instead.
