Hi,
I wanted to add the steps for restoring to your previous version, which I
had to discover after a harrowing session, as I selected to uninstall the
new files through synaptic and it deleted almost the entire Ubuntu :-( .
You should keep the pango files of your distribution handy, by going to the
CD/DVD (/media/Ubuntu 10.04 LTS i386/pool/main/p/pango1.0/) or downloading
from the net.
libpango1.0-0_1.28.0-0ubuntu2_i386.deb
libpango1.0-common_1.28.0-0ubuntu2_all.deb
When you want to restore to your original packages
please open terminal and change to the directory, where you kept the
original packages
$dpkg -i --force downgrade libpango*.deb
Logout and then login.
Your system should be back to normal.
Hope this helps.
Something similar may be needed for those using .rpm files.
In case you have not tested, hope this helps.
Regards
Arjun
