How to set iceweasel as the application to open http hyper links in icedove?

[Michael Yang <michael.yxf@gmail.com>]

Hi:

I'm working on Debian lenny/sid, with the IceDove 2.0.0.4 installed on 
my machine.

When I click a hyper link in icedove, I'd like one browser, for example, 
iceweasel, to open this link.
I didn't find any where within icedove to set this option. Could anyone 
point it out?
There is no response now when I click the link.
I have set the iceweasel as my default browser, icedove as default mail 
client on my machine, and also it works fine when I click the link in QTerm.

Thanks.
Michael.
