Yes, I can fully reproduce. See these error messages on the console:
digikam(5323)/digikam (core) Digikam::readPGFImageData: Error running libpgf (
2 )!
digikam(5323)/digikam (core) Digikam::ThumbnailCreator::loadFromDatabase:
Cannot load PGF thumb from DB 

This means the data is loaded from the db, but libpgf fails to load the data
with error code 2. Apparently this happens only with every second or third
image.
Backtrace of the thrown exception:
