Missing Integration as default program for opening .zim files

[robo47]

After installing ZIM I expect to be able to directly open .zim files with a double click, but it only appears in the right-click menu as "Open with ZIM Desktop Wiki".

Going via right-click to properties -> "Open with" even after clicking "Show other applications" does not show ZIM anywhere.

i have the same issue with "gtranslator"

Status changed to 'Confirmed' because the bug affects multiple users.

Seem to be an issue in nautilus or whatever component does the lookup
for the relevant application.

Notes (on my system):
* /usr/share/applications/zim.desktop exists
* it correctly lists application/x-zim-notebook
* it is index, the same mimetype shows in /usr/share/applications/mimeinfo.cache
* in nautilus the properties of the zim.notebook file show the same mimetype
* double clicking in nautilus goes to a text editor

Expected:
* double clicking in nautilus opens zim

Additional notes:
* xdg-mime query filetype also gives the correct mimetype
* xdg-open again opens in text editor (wrong) -- probably uses gnome component
* gnome-open also goes to text editor (wrong)
* mimeopen does open the file with zim (correct)

So think this bug should be assigned to proper Gnome component - not
sure which project that would be.

I confirm the same problem after installing zim 0.54-1 on the following system:

Ubuntu 12.04.2 LTS precise
Kernel 3.5.0-36-generic
architecture x86_64

Zim was listed as an alternative, but not the standard application for opening Zim notebooks. From the context menu, however, it could not be assigned, as it did not appear in the 'other applications' list (as described in the original bug report).

The problem was fixed by adding the following line to /etc/gnome/defaults.list:
application/x-zim-notebook=zim.desktop

Zim now is the default application for opening Zim notebooks. But it still does not appear under 'other applications'.
