Enabled group-per-window setting causes dconf write on each window switch

[Oleg O Andreev]

When group-per-window option is enabled, each time active window is switched "org.gnome.desktop.input-sources.current" key is updated by indicator-keyboard-service. This key is updated even if it has previously stored the same value.

Update causes dconf-service to write the user config file ~/.config/dconf/user to disk. On all filesystems except btrfs this write is followed by fsync. which causes immediate disk activity upon each window switch.

It would be nice if indicator-keyboard did not update the "org.gnome.desktop.input-sources.current" with the same value.

A simple patch with the proposed solution is attached to this bug report.

Hi Oleg, thanks for your patch! I modified it only slightly since trunk has changed a bit, but your patch still looks good.
