Digikam slow at startup

[Kenneth Ingham]

The 5.7.0 appimage is still slow at startup.  It took 1 min, 55sec to
display the window when I started it at the command line.

Also, the messages on the terminal stopped for most of this time.  It
printed a bunch of messages ending with:

digikam.general: Added root album called:  "KIPHOTO"
digikam.general: Added root album called:  "Photos"

It was only a few seconds at most to get to this point.  It then was
silent for most of the 1:55, then continued with:

digikam.general: Using  8  CPU core to run threads
digikam.general: Action Thread run  1  new jobs

Once the console messages started up again, it was at most a short delay
before the window appeared.
