I'm experienceing strange plate solving crashes with version 3.5.1 when using external source-extractor and local astrometry on pictures taken with version 3.4.0!
Luckily the internal plate solving works, so I can going on with my projects. But I really want to know what's happening! By mischance the full log of astrometry doesn't provide any clues, as source-extractor stops with "old" pictures all of a sudden while listing the background maps creation!
