OK - here are the event logs from the time the game crashed in the bar (the texture where the logo should be was blank again) - still don't know exactly when this happens or what the pattern is. I have an idea, but would need some time to investigate.
Edit: I thought that it might be caused by Alt-Tabbing to Windows, but I could not confirm it. Then it occured to me that maybe it happens when the news content I want to display is different from the previous one that I had displayed without problems. E.g. if story progresses or you dock to a different faction base (anything that triggers content change in the news I guess). That's pretty much all I can think of right now. Adding second pair of events from after the second crash.
Also, everytime I launch the FL I see this one error event in the log right when FL goes full screen BUT it does not seem to do any harm (nothing crashes) and I'm not sure what it is...
