All images deleted

Maybe this bug should be reported to drupal core instead. Twice it has deleted (!) all my images in the public folder... And I see a strange message in the "reports" list: The file public://galerie-13/0062-6f26189b9cea13d3bf043b2bd9abe557.jpeg was not deleted, because it does not exist

(User: anonymous, severity: notice)

I have created a directory-galerie and uploaded everything, everything looks fine.. The next day when I surf to the site all images has been deleted. The thumbs still exist and the db looks ok also, nothing deleted there. I'm using Drupal 7.12 with the standard installation theme.

Seems its this function in include/file.inc that tries to remove:

/**
* Delete a file without calling any hooks or making any changes to the
* database.
*
* This function should be used when the file to be deleted does not have an
* entry recorded in the files table.
*
* @param $path
* A string containing a file path or (streamwrapper) URI.
*
* @return
* TRUE for success or path does not exist, or FALSE in the event of an
* error.
*
* @see file_delete()
* @see file_unmanaged_delete_recursive()
*/
function file_unmanaged_delete($path) {..

I think its the file module that does this.. and its a very stupid behaviour..
