Error when indexing special hidden windows folders in 9.0.15

[dhoffend]

This is a follow up to the already closed but unfixed issue #1521

The error still exists. It fails to index special folders inside the windows "Documents" folder. The issue has been closed by @killing with the comment that it has been fixed with 9.0.6 but I can't find any commit that's targeting that specific case of hidden system folders that are unable to be indexed.

According to others the issue still exists in 9.0.6, in 9.0.8 and I can confirm that it still persists in 9.0.12 and 9.0.15

Here are my log snippest from a windows 10 system (with german locales of the those mentioned hidden special folders)

A part from the logs I guess I don't need to provider new screenshots as they would be exactly the same compared to #1521
