Try turning on your Valentina log also so you can see what happened before crash. Then you can put that log and the one from your Realbasic crash log in Mantis. A crash on quit makes me suspect something to do with VDatabase_Close, VServer_Destructor and Valentina_ShutDownClient which you can get a crash when operating the demo for RunRev (I just reported that in Mantis with screen shots as well).
