rescanning media library problems - removing deleted files ??

Hi. First, thanks for all the work you do. I've never said that before although I've used LMS and its predecessor for more than a decade.

I run Linux Mint 17 and have installed LMS nightly build logitechmediaserver_7.9.1~1508251793_amd64.deb

This is what happens: LMS rescans the library every hour (per a cron job I set up in Mint). Mostly it goes fine but then it does what it is doing now:

It says "Rescanning Media Library ... Removing deleted files (1627 of 20) and this just seems to keep going even though, in the end, I don't think any files are actually deleted. But I could be wrong.

This happens fairly regularly but is sometimes interrupted when I update or reinstall the software.

I don't know what this means or what to do about it. I have a screenshot if you want to see it.

Clicking Settings and then the link to view scanning progress and then clicking on the "abort scan" feature does nothing.

Thanks.
