Playlist opens a very long time

[user623]

Hello.
I have 3400 files in my library.
I set "hello" tag to 500 of them.

Then i create auto playlist "all without hello tag". When i click on it - it take 15-20 second to load and show files.
If i create hello2 tag and also exclude it - playlist open up to 30 seconds. All this time mezzmo "not responding".

And on clients (android mediahome) this playlist does not open at all.

I think it's a bug, please fix it.

UPD: I get this problem only when use play count rule ( Play count -> Is -> 0 ) with tag rule ( Keyword -> does not contain -> hello)

UPD: Category1 and Category2 - 1000 and 300 files
Rules set:

All:
Category -> does not contain -> Category1
Category -> does not contain -> Category2
Play count -> Is -> 0

Make mezzmo "not responding" until shutdown thru process manager.
