gtksourceview-sharp should no provide nemerle.lang

When upgrading Hoary today the gtksourceview package seems broken. Not sure if
these things should be reported, so please tell me that aswell.
I saw no report about it in the bugzilla atleast.

apt reports that
"/var/cache/apt/archives/libgtksourceview-common_1.1.90-0ubuntu1_all.deb
(--unpack):" tries to overwrite
"/usr/share/gtksourceview-1.0/language-specs/nemerle.lang" that also is in the
package "libgtksourceview-cil".

Since its a development branch, i do expect these things to happen, but should i
report them, or do you people see them automaticly and correct them?
Or should these things be reported, aswell as normal bugs inside programs?

Confirmed on my system.

Also confirmed on the forums: http://ubuntuforums.org/showthread.php?t=10918

It seems removing libgtksourceview first will resolve the issue, but it makes
you remove MonoDevelop and gedit, among other things, so is somewhat unacceptable.
