I think I was clicking on a ship. Will try and reproduce, but it's about 8 minutes into a 10 minute autosave cycle. :/
Crash save and screenshot are in Krob-1.5.0.1-crash.zip
Updated: Crash did not repeat itself, but it was the second in a few hours. Maybe it's caused by having multiple races with research stations on the same planet (see other bug report). ;)
