panel items look weird

How do I fix this error? I know this can be done by restarting the panel, but this is not convenient because every time you boot you need to do it.

There is a bug for this one already:

https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/660877

It doesn't have any other people saying anything in it, so I'm not sure whether it is known to the devs. I have had a look for a fix, and it seems like this will work:

create ".gtkrc-2.0" file in your home firectory, and put this in it:

include "/usr/share/themes/Ambiance/gtk-2.0/gtkrc"
gtk-icon-theme-name = "ubuntu-mono-dark"

Hope this fixes it for you :-)
