Lots of uploads fail due to problem "moving" files from the stash to the target file name.
- Upload Wizard shows an error that it cannot find the image in stash (maybe already moved)
- After clicking retry, Upload Wizard tells you that there is already a file with such a name
- Upload Wizard tells you that "an unknown error" occurred
- No upload log entry, no description page: https://secure.wikimedia.org/wikipedia/commons/wiki/File:Rabenhof_10.JPG
- Page created with wikitext but image missing (McZusatz will be able to give you an example if you need one)
- Wikitext created, image twice in revision history
