FS#1312 in mediamanager problems with filenames having capital letters

By using mediamanager in the Dokuwiki through the icon in toolbox or directly accessing lib/exe/mediamanager.php I find that I can attach to the wikipage some document with capital letters but I can not open or delete it.

For example:
In directory ../data/media/books I have a file "Z.djvu", I can click on the first icon beside the name and it inserts

{{:books:Z.djvu}} or something like that

in the wikipage, which is correct. But pressing the magnifying glass button is says

Not Found

and by pressing delete button it says

.../media/books/z.djvu" couldn't be deleted - check permissions.

In the report, it already changes the case of the file.
