Public bug reported: Frequently - but not always - on a check for updates, update-notifier reports an error in the notification area instead of showing that updates are available:
"An error occurred, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was: ' Unknown Error: '<class 'KeyError'>' ("The cache has no package named 'wine1.6-i386'")'. This usually means that your installed packages have unmet dependencies" wine1.6-i386 is an i386-architecture package on my system, a foreign- arch multiarch dependency of wine1.6. update-notifier appears to not cope correctly with foreign-arch packages.
