iceweasel always requesting to be default browser

[Roman Stöckl-Schmidt <roman@stoeckl-schmidt.de>]

Hi guys!

I've got a really strange behaviour in iceweasel since upgrading to the 
newest package in etch (2.0.0.2+dfsg-3).

When I ran it for the first time after upgrading it asked wether I 
wanted to set it as the default browser. Since the previous version had 
been my default browser and I intend to keep it that way I was surprised 
by the prompt, but confirmed it anyway. Now the strange thing is that it 
keeps aksing the question every time it start it, stating that it is not 
the default browser atm and wether or not I want to make it.

Help greatly appreciated as always.
Cheers, Roman.
