Packages broken by Emdebian

A few days ago I made an aborted attempt to install Emdebian-grip on a 
Wheezy amd64 system to get the ARM cross compiler. I wasn't comfortable 
that it has dependencies on Squeeze and bailed on the attempt without 
selecting any Emdebian packages for installation. I did however run an 
apt-get update/upgrade cycle with the Emdebian repos active in 
apt.sources. This seems to have picked up Emdebian packages that now 
cause conflicts after trying to upgrade to Debian 7.4:

$ apt-get upgrade

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 gnome-bluetooth : Depends:
 gir1.2-gnomebluetooth-1.0 (= 3.4.2-1em1) but 3.4.2-1 is installed
 gnome-panel : Depends: gnome-panel-data (= 3.4.2.1-4em1) but 3.4.2.1-4 is installed
 libxcb1 : Breaks: libxcb1:i386 (!= 1.8.1-2+deb7u1) but 1.8.1-2+deb7u1em1 is installed
 libxcb1:i386 : Breaks: libxcb1 (!= 1.8.1-2+deb7u1em1) but 1.8.1-2+deb7u1 is installed
 libxcb1-dev : Depends: libxcb1 (= 1.8.1-2+deb7u1em1) but 1.8.1-2+deb7u1 is installed
E: Unmet dependencies. Try using -f.


Trying to force the installation of the Debian packages will result in uninstalling critical system files which I can't risk.
Can any one help on what I should do to fix the package dependencies?
