If qgis (including the grass plugin) is installed from the 
repository indicated in the qgis download page:

 http://ppa.launchpad.net/qgis/unstable/ubuntu jaunty

qgis crashes at startup with:
/usr/bin/qgis.bin: symbol lookup error: /usr/lib/libqgisgrass.so.1.2.0: 
undefined symbol: G_no_gisinit

Installing using
as repository works fine.

Also, Synaptic does not list libqgis.* when qgis is used in the Search field
(you must write libqgis to see libqgis* items listed) and
does not select libqgis* for removal when qgis is selected for removal (even complete removal). As a matter of fact, I had both libqgis.1.1.0 and libqgis1.2.0, although this duplicity
does not seem to have been a problem.
