Hi,
evolution appears twice in the GNOME applications menu, once in the Office
section and once in the Internet section. The Icon in the Office section reads
"Evolution Mail and Calendar" and ist installed via evolution-common:
/usr/share/applications/evolution.desktop; the other one reads "Evolution Mail"
and is installed via evolution: /usr/share/applications/evolution-mail.desktop.
I see that Evolution is mainly used for email, which justifies the icon in the
Internet section, but is also used for task planning and calendar, which
justifies the icon in the Office section. However, having two separate icons in
both section is simply confusing. Please decide for one of both to install. If
you're asking me, doing emails can also be considered an Office task and is not
necessarily connected to the Internet, so I'd stay with the icon in the Office
section and drop the other one (which is, BTW, a debianism added in debian
/evolution-mail.desktop and installed via debian/evolution.install).
Cheers,
Fabian
