If you click on the "Upload a new version of this file" link, you will never be allowed to upload a new version of the file. It will allow it to start uploading, then claim that the file has no extention when it's done. As an annoying secondary bug, which might matter if it weren't for the above, it truncates the filename after any apostrophe. This does not affect normal upload, so it's merely awful, instead of destroying Wikipedia completely. But please, please fix this quickly.
