digiKam 5.5.0.1 with MySQL - "Preparing collection scan..." takes ages

[Guardian]

Hi, i installed digiKam on a Server 2012R2 with MySQL.

 

Now when I run digiKam it takes ages to start the application.

If it finally has started, you can browse folders, but they are mostly empty and digiKam crashes pretty fast.

 

Do you know this issue?

 

Greetings

Timo
