problems installing evolution on debian/sid

[Cristi Banciu <mufa@alibiduba.bounceme.net>]

Hi, when I try to install evolution I got the following errors.
I am running debian sid.
Any idea what is wrong and how could I fix it ?
Thank you!

#cat /etc/apt/sources.list
deb http://ftp.de.debian.org/debian sid main contrib non-free
deb http://ftp.de.debian.org/debian-non-US/ sid/non-US main contrib 
non-free

#apt-get install evolution

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:
