Bug#404733: dpkg error upgrading iceweasel

[Fabiano Manoel de Andrade]

I've solved the problem unninstalling the packages flashplugin-nonfree
totem-mozilla and sun-java5-plugin. After this upgrade the iceweasel and
installing again flashplugin-nonfree totem-mozilla and sun-java5-plugin. Now
all is working.

Fabiano.
