Comment 4 for bug 1452849

to reproduce:
 boot the machine... it show up a warning that a application had a internal error.
 Consequences... well, it is annoying, but other than that we don't see any. Maybe one less background (and possible useless) service

This machine is being upgrade since many releases, probably a new clean installs don't have it.
Maybe canonical can release a tool that shows what packages should a default ubuntu install should have (flagging the missing ones) and what packages are installed and would not been in a default install. One could then cleanup any old packages that might be messing the system
