Default ubuntu-bug segfault

Hi,

I noticed a problem with "ubuntu-bug" tool on 12.04 desktop-i386
build. When I try to use it with non existing package name it
segfaults. This happens every time, I am running ISO in VirtualBox
4.1.10 on Kubuntu 11.10 host. More details and exact info how to
replicate below.

I hope it is useful,
Regards,
Jacek



Application: python2 (1.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.2.0-21-generic-pae i686
Distribution: Ubuntu precise (development branch)

-- Information about the crash:
I am testing in VirtualBox 4.1.10 on Kubuntu 11.10 host system. VM
config is 1vCPU, 768 MB RAM, 10 GB hard drive. This happens on
precise-desktop-i386 build from 31st of March and can be reproduced
every time.
Steps to reproduce:
* Boot into the Live CD and click "Try Kubuntu"
* launch konsole (Alt+F2 and type "konsole")
* try reporting a bug for a package which does not exist for example:
$ ubuntu-bug bacon-sarnie
* a pop up saying "Package bacon-sarnie does not exist" appears
* click OK to dismiss pop up - this triggers segfault
