apport-collect reports "HTTP Error 401: Unauthorized" even though permission has been given

The same story:
apport-collect -p network-manager 371711
Logging into Launchpad...

launchpadlib.errors.HTTPError: HTTP Error 401: Unauthorized

The same thing here.

launchpadlib.errors.HTTPError: HTTP Error 401: Unauthorized

Same here. But what worked for me was:
>Error connecting to Launchpad: HTTP Error 401: Unauthorized
>You have to allow “Change anything” privileges.

rm -fr ~/.cache/apport/

then run apport-collect command again enter an URL and hit the last button “Change anything” ! Press ENTER and wait...:-)

Thanks Ľuboš Rendek
Solved for me.

Architecture: i386
DistroRelease: Ubuntu 9.04
Package: apport 1.0-0ubuntu5.2
PackageArchitecture: all
ProcEnviron:
 SHELL=/bin/bash
 PATH=(custom, user)
 LANG=en_US.UTF-8
Uname: Linux 2.6.28-11-generic i686
UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare

Solution provided by Ľuboš Rendek also worked for me. Thanks!

Apport should detect the (invalid) cache and purge it automatically, or provide a confirmation prompt.

Lubos' solution doesn't work for me:

---
$ rm -fr ~/.cache/apport/
$ ls ~/.cache/
album-art compizconfig gedit rhythmbox ubuntuone
banshee-1 Empathy notify-osd.log tracker
$ apport-collect -p ubuntuone-client 397027

The authorization page (https://edge.launchpad.net/+authorize-token?oauth_token=XF3mcrHSChLxwpC6fXCG) should be opening in your browser. After you have authorized this program to access Launchpad on your behalf you should come back here and press <Enter> to finish the authentication process.

You have to allow "Change anything" privileges.

Erigami, bug 397027 is a duplicate, that might be the reason. Does it work for other bugs for you?

For me, uploading apport-collect data to bug 397027 works, so it's not a general bug with duplicate bugs or apport-collect.
