broken dependency

[Matthes]

When 'completely remove' it I get the same error. There aren't any other change suggested when I mark it for removal.
How can I search/remove the package via nautilus?
I think that my sources are okay.

dpkg-reconfigure lbsdl-image1.2-dev && sudo apt-get remove --purge libsdl-image1.2-dev
output:
Package `lbsdl-image1.2-dev' is not installed and no info is available.
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
/usr/sbin/dpkg-reconfigure: lbsdl-image1.2-dev is not installed
