[gnome-flashback] Theme problem with panel handles?

[Thomas Pönitz <tasptz gmail com>]

Hello,

I'm using Ubuntu 14.04 and the ambiance theme.

There is a display problem with the handles of a non-expanded gnome panel.
See my screenshot:

Is this a bug in gnome panel or in the theme?

Thanks,

Thomas
