Bug description

I have running NC 28.0.3 with Samba shares. As one of the users reported - I found that when "Show folder description" is enabled it stops rendering folder pages. In the console there is reported HTTP 500 status error.

On the server side I can see this reported here (note: the folder "odměňování" exists, it is Samba share, however "Readme.md" doesn't)
