Comment 18 for bug 1751734

@ who might be interested:

A completely naked version of Calibre portable 3.19 also hangs when it has to handle a big library.

I am almost convinced that it has to do with the split library view introduced in 3.17,
But saying that is a crime...........

But 3.16 is working like a charm, I stay with that.

Sticking your head in the sand reminds me of a big bird......that has long toes also.....
