On Ubuntu 12.04, Gnome, with XMonad window manager, the pwsafe systray icon shows up at the top left corner, over the Gnome panel.
It stays on the workspace where pwsafe was started, so it's not too much of an inconvenience.
This doesn't bother me much, just thought you might like to know.
The problem with the systray icon on Linux surfaces on many different
combinations of display manager/window manger. Its basically an
artifact of the dissimilar implementations on different versions of Linux.
We use the wxWidges UI library, which runs on top of Gtk (which I
believe , so unless one of these two libraries take care of the
underlying incompatibilities, there isn't really much we (pwsafe) can do
about the systray icon.
Ah, I see. It probably comes down to conforming to standards such as those from http://www.freedesktop.org/
I'll see if I can figure out enough to log issues upstream.
I assume the same answer applies to the distorted pwsafe icon I see in my system tray, as shown in the attachment.

The system tray icon is no longer distorted (and hasn't been for a while). There was a period of time where clicking on the system tray icon only worked on the very edge of the icon, and this is no longer the case either. However, the icon that appears is sometime the pwsafe icon, and other times it duplicates the icon to the immediate left or immediate right. In the uploaded attachment, the pwsafe icon is the rightmost of the two green Skype icons that look like bubbles; hovering the mouse pointer over the leftmost one gives the tooltip, "hughhyatt - Skype™", while hovering over the rightmost gives, "/home/hugh/.pwsafe/default.psafe3".
The icon functions correctly when left- or right-clicked, so this is not a big problem; it's more of an annoying quirk.
