panel reports an error but no details

Binary package hint: gnome-panel

Hello! I recently upgraded to Lucid, and I started having this bug.

When I log-in, every time, I receive two identical error dialogs. They have, in bold, “The panel encountered a problem while loading "OAFIID:GNOME_KeyboardApplet".”, and in normal text “Do you want to delete the applet from your configuration”. There are only two buttons, marked “Don't Delete” and “Delete”.

I've no idea why there are two dialogs, AFAIK I've only a single keyboard applet on my panel.

The bug, as I see it, is not so much that the error appears, but that there's no visible way to track down what actually happened. If I don't delete the applet, it's still there in the panel, and it appears to work more or less correctly.

(I believe the error is caused by the fact that I'm using a non-standard (home-made) keyboard layout. The applet doesn't display anything when I'm using it, although it displays the country name for other layouts. However, despite the error messages and the lack of a visible name, my layout seems to work correctly.)

Again, this bug report is not about the fact that the error happens, but that the error dialogs don't present any way of tracking down the problem, only to make it go away by removing the applet.
