iceweasal vs long urls. Long url wins, iceweasal doesn't

[Gene Heskett <gheskett@wdtv.com>]

Using a distro based on wheezy, configured with a real time kernel, but 
not running it. Using a 64 bit 3.2.0 instead. And because the wheezy 
kmail is font broken, using TDE R14, where kmail Just Works(TM).

Over on another list, I've a guy using dropbox to post some .png images 
of a circuit board he has designed.

Unfortunately I cannot see those images because dropbox is using %20 for 
spaces in the returned URL.  But between my clicking on the link in 
kmail 1.13.7, and iceweasal, the %20's are being converted to spaces by 
the time I see iceweasal's address bar contents, so of course I am 
looking at dropboxes fancy 404's page since spaces aren't allowed in a 
URL.

This translation should not be taking place IMO.

Is this something I can fix with an iceweasal about:config option?
I have looked without seeing a likely suspect.

Thanks all.

Cheers, Gene Heskett
