unable to install experimental iceweasel release (using debian testing)

[Jarrett Chisholm]

Hi

i'm trying to install iceweasel release from debian experimental (deb
http://ftp.ca.debian.org/debian experimental main) via the instructions
given on mozilla.debian.org.

My system is running the latest debian testing.

Unfortunately, I'm unable to install, as I get the following issue:

jarrett at debian:~$ sudo aptitude install -t experimental iceweasel
The following NEW packages will be installed:
  libmozjs19d{a} xulrunner-19.0{ab}
The following packages will be REMOVED:
  xulrunner-10.0{u}
The following packages will be upgraded:
  iceweasel
1 packages upgraded, 2 newly installed, 1 to remove and 683 not upgraded.
Need to get 16.8 MB of archives. After unpacking 18.6 MB will be used.
The following packages have unmet dependencies:
 xulrunner-19.0 : Depends: libnss3 (>= 2:3.14) but 2:3.13.6-2 is installed.
The following actions will resolve these dependencies:

     Remove the following
packages:                                                                        

1)    
gnome                                                                                               

2)    
gnome-core                                                                                          

3)    
iceweasel                                                                                           

4)    
task-gnome-desktop                                                                                  

5)    
xul-ext-firebug                                                                                     


     Keep the following packages at their current
version:                                                 
6)     xulrunner-19.0 [Not
Installed]                                                                      


     Leave the following dependencies
unresolved:                                                          
7)     task-desktop recommends task-gnome-desktop | task-kde-desktop |
task-lxde-desktop | task-xfce-desktop
8)     task-gnome-desktop recommends
gnome                                                                 
9)     task-gnome-desktop recommends iceweasel

The alternative solutions are not disirable (i.e. don't install, or it
asks me toremove a crap tonne of packages)


Any idea how I can fix this?  As a side note, if I change the
sources.list to use the mozilla ESR release (deb
http://mozilla.debian.net/ experimental iceweasel-esr), aptitude doesn't
seem to have an issue.

Cheers
