Comment 5 for bug 564351

This is not a duplicate of bug #560095, nor is it the same problem as in bug #564506 (although directhex's patch incorporates this fix). The problem here is that the postinst & postrm fragments which actually call the late-gac installer weren't being copied to the binary deb because dh_installcligac was being called after dh_installdeb.

You can verify this by running “gacutil -l | grep appindicator”. With libappindicator0-cil 0.0.19-0ubuntu3 this returns no results, because the library hasn't been installed into the GAC
