[Reportbug-maint] Bug#620224: reportbug crashes after selecting package (specific package)

[draeath]

Package: reportbug
Version: 4.12.6
Severity: important

On a fresh Squeeze installation, reportbug is unusable (GTK
interface). On the first run, you are able to enter your name, email,
SMTP host, proxy etc.
When attempting to use it to report a bug, I can go as far as entering
the effected package name. On selecting continue, the window
dissapears (and the following text is printed to the console if you
run it from such:

/usr/lib/pymodules/python2.6/reportbug/ui/gtk2_ui.py:476:
