I am using Ubuntu 12.10.
I am unable to see the bookmarks in Nautilus, although right clicking on "Personal Ordner"(German version) opens a list of the bookmarks. The corrupted screen (see the screenshot below) shows the bookmarks in a sub-window only about 5 mm wide!
I have tried reinstalling Nautilus with Synaptic, without however any success.
Any ideas about how to resize the width of Nautilus' sidebar?
