GNOME Bugzilla – Bug 634707
Non-square legacy icons display incorrectly

Created attachment 174351 [details] Broken gTimelog icon. gTimelog has a rectangular persistent tray icon, about three times wider than it is tall. It does not display correctly in the Shell: it's crushed into a tiny square. Screenshot attached. gTimelog is using python-eggtrayicon 2.25.3-6 from Debian Unstable.
The end of https://bugzilla.gnome.org/show_bug.cgi?id=634820#c5 has a note of how I think you'd go about fixing this, though I didn't actually try to do so.
Having tried a recent version of gTimelog, this seems to be fixed.
