I had a problem with this package. As the armhf image I use is based on Debian unstable and I have it updated. One package required to be installed does not exist in unstable: libv8-22.214.171.124
So, in order to install your package on unstable you have to download and install
http://ftp.us.debian.org/debian/pool/ma ... _armhf.deb
sudo dpkg -i chromium-inspector_16.0.912.75~r116452-1linaro1_all.deb
sudo gdebi chromium_16.0.912.75~r116452-1linaro1_armhf.deb
After that, chromium should run fine on unstable (at least as it currently exists). I hope this helps anyone else that might have similar problems getting this package installed.
