black bar in gnome-panel when updating something

[Samuel Mehrbrodt]

Binary package hint: gnome-panel

Look at the screenshot. The black bar appears sometimes when an icon changes in the panel, but not always.
I noticed this in karmic yet and in lucid also.

This is because update-notifier attaches the libnotify notifications to a tray icon - there was a similar issue in empathy too

I am also effected by a black bar although slightly larger in width. I also noticed the right clicking on the panel to bring up the properties and then expanding the size of the bar by a couple of pixels would cause the bar to disappear. Afterwards you can reduce the width down again to it's normal value.

Can someone close this as WONTFIX? I didn't notice this in newer versions and Lucid's EOL is this almost there.
