Comment 9 for bug 1029531

Right, so after some more debugging, thanks to Steve for parsing the apt output, the total list of problems is the following.

 - update-notifier-common attempts to run patch but doesn't depend on it, the failure is ignored so not causing a critical bug
 - the resolver fails to decide to remove librasero-media0 to make launchpad-integration installable
 - the resolver tries to keep the old evolution-plugins, breaking libnspr in the process
 - libgnome2 is required by the upgrade but not on the media
 - openoffice.org-core is needed by the upgrader but doesn't exist in the archive
 - some other openoffice.org packages are required by the upgrader but not on the media
 - the upgrader requires ".*screen.*" to be installed instead of "^screen$" making the upgrade fail if any package containing the work screen is removed by the upgrader

And the matching list of changes:
 - update-notifier-common needs to depend on patch
 - launchpad-integration needs to break on libbrasero-media0
 - libnspr4-0d needs to break on evolution-plugins (<< 3.2.0-0ubuntu2)
 - seed libgnome2 on alternate
 - add transitional package openoffice.org-core to openoffice.org
 - fix removal blacklist to use "^screen$"
