Systray icon cropped in GNOME 3
Bug description
Since GNOME 3.6 there is a new systray that has much larger space for icons - 48x48. The applications can still use smaller icons, they are then centered (dropbox or goldendict on my screenshot).
Unfortunately Gajim exhibits a weird bug - its icon (I presume 32x32) is centered, but then it is cropped from bottom right. See screenshot.
The icon should be displayed in full.
I think this bug was present even in older version of GNOME 3, with a 24x24 systray, it was just not so visible. This is a screenshot from ticket 7225: https://trac.gajim.org/attachment/ticket/7225/just_started.png
If I try a StatusIcon demo and use the same icon, it is displayed properly. So the problem is definitely somewhere in Gajim.
