Bug#559711: reportbug crashes after entering package

[Debian]

Package: nautilus
Version: 4.8
Severity: important

I just tried to open a bug on package kdebase-workspace-bin.
When i enter the packagename in gnome the window disappears and the following
errors will stay on the shell:

user at PC:/tmp> reportbug
