Every few days I get some new packages that are broken. They have dependency issues or the configuration failed. In the most cases it's fixed within a day. But there are a lot of packages that need several days before they are fixed.
We can post these problems on launchpad but from my experience I know there is a high chance that such minor things will be overseen. I have even the experience after I posted here on natty testing some of such issues they was fixed in a few hours (maybe somebody who could fix it read it). And because these problems are very recently I thought about a thread that lists all of these problems.
I want to begin with a few broken packages:
avahi-daemon (fails on configuration)
dbus (fails on configuration)
libpurple0 (dependency issue)
pidgin (dependency issue)
