Upload a file to the wiki, then delete it. Now remove the backup version of the deleted file from image/deleted/... and then try to restore the deleted file.

You will get something like:

Image:Test.png has been restored
Consult the deletion log for a record of recent deletions and restorations.
Error undeleting file: Could not find file "deleted/0/g/m/0gmrfwcz98nttgzo0f15m7t2kc8wvuk.png".

Also, in the deletion log, an entry is added:

17:15, 24 January 2008 Huji (Talk | contribs | block) restored "Image:Test.png" ‎ (1 revision restored)

Both of these are undesirable. Neither should a "has been restored" be shown, nor should an entry get added to the deletion log.
