Not allowed to view bug report

I've emailed the owner of that bug, asking him to consider making it public.

Hi all,
 Jeroen I am the owner of the bug. I dunno myself why its marked private. Perhaps some of the stuff there is private. I would recreate the bug-report here itself so you guys can look at the bug and see if its similar or not.

apt-listchanges crashed with OSError in display_output()

The thing is apt-listchanges uses some pager or stdout to show the changes file. I've put mine to show up in another pager window. This is cool when you have some x window manager like metacity or some other

Now sometimes while updating/upgrading for some reason or other specially when running alpha builds sometimes x windows break but one is able to still use the single (recovery) console to drive updates and upgrades. But if you try to do that having apt-listchanges the application crashes and one is not able to update/upgrade unless one uninstalls apt-listchanges. thereby defeating the whole purpose of apt-listchanges.

There is obviously some design issue or someway they need to guide us users so we can use in either eventuality.

There is a traceback to that error.

Shirish: it's not my call whether that bug should be private or not. But if you look at the activity log for the bug, you should be able to see who made it private and contact that person.
