Icedove 5 dependencie problem on Debian wheezy

[Arie de Jonge]

I tried to upgrade Icedove 3 to Icedove 5 using the mozilla.debian.net 
repository

deb http://mozilla.debian.net/ squeeze-backports icedove-release

I get the next dependency problem, and upgrading is impossible
> icedove:
>  Depends: libhunspell-1.2-0 (>=1.2.11) but it is not installable

The installed version of libhunspell is 1.3.2-4 (testing)
