MTK GPS Datalogger Device Control

I've been using version 1.68.28 and wanted to switch to the latest 2.X since it adds the "New Track after <distance>" filter. But 2.X.1535 and older seem to have a problem with extraction/displaying the thumbs on the map tab. If I select a reasonable number of images for tagging (let's say 50) they're not displayed and I get a lot of Exceptions on the terminal:

Exception in thread "Image Fetcher 2" java.lang.OutOfMemoryError:
