For some thumbnails I now get a 404. Not sure that if is related to the update or changes to the 404 handler? I.e. if you look at http://test2.wikipedia.org/wiki/User:JanGerber/commonstest all thumbnails currently return an error.
https://bugzilla.wikimedia.org/show_bug.cgi?id=41371 provides an overview of imagescaler/thumbnail bug reports (click on "Show dependency tree" to get a full list with bug summaries). There are some recent reports in Bugzilla that might be related to the Ubuntu upgrade and this should be the easiest way to find them.
