The software is packaged, but lintian is not clean: E: evolution-tray: pkg-has-shlibs-control-file-but-no-actual-shared-libs W: evolution-tray: postinst-has-useless-call-to-ldconfig W: evolution-tray: postrm-has-useless-call-to-ldconfig
Most likely you ran into this long-standing debhelper bug: http://bugs.debian.org/204975
To work around it, either pass -X to dh_makeshlibs or, if you don't have any public libraries (which is the case here), don't call dh_makeshlibs at all.
(BTW, such basic packaging questions are better asked at the debian-mentors mailing list.)
