Autodetect subtitle files doesn't work for SMB share

With option "Autodetect subtitle files" under Video/OSD enabled VLC isn't able to load subtitles if file located on SMB shared.

It doesn't matter whether file in subdirectory or in same directory as video file itself.

If I add subtitles manually VLC correctly uses them.

SMB share is password protected and doesn't have guest login.
