Just a guess, that this might be related to Tracker’s Evolution plugin.

What is the problem? Make sure to install `evolution-dbg` [2].

I think, you should report a bug at Ubuntu’s bugtracker Launchpad.
Hopefully the Ubuntu maintainers can point you to some repository
providing newer versions. If not you have to build the package
(evolution and evolution-data-server) yourself which is not that
difficult.
