psi-plus.desktop misses entry StartupWMClass

[Bernhard]

the excellent instant messenger psi-plus, uses the window class "psi". Thus, after launch it will be displayed as an extra icon in both unity and gnome-shell.

This can be easily fixed by adding the following entry to the psi-plus.desktop file:

StartupWMClass=psi

Bernhard

I have no Unity or Gnome 3. Could you make two screenshots to show the difference? Thanks.

[Bernhard (xro)]

in the screenshot you can clearly see, that without StartupWMClass=psi set in /usr/share/applications/psi-plus.desktop, psi-plus show's up as two icons in the gnome-shell as opposed to just one as it should.

[Tehnick (tehnick)]

These are two different windows:
1) window with roster
2) window with chats

Do you really want to miss possibility of switching between them?
I do not think that other people will be agree with you...

[Bernhard (xro)]

you misunderstand how window switching in gnome-shell and unity are supposed to work. The dock on the left is not a windows switching mechanism but application specific.
You switch to an application, then you switch between it's windows. Or directly to a window of an app by right-clicking its dock icon (see screen-shot). Showing two windows of an app as separate icons is definitely wrong.

Also, setting StartupWMClass is just a workaround, the real problem is that the psi-plus executable is not named psi, or alternatively psi-plus claims its X WindowClass to be "psi" when it shouldn't.

I've tested it in my KDE and LXDE. And there is no difference to me.
Also this key is valid [1] in the freedesktop.org standard.
So I am going to add this option in the next upload.
Thank you for the bug report.
