[1.0 CTD] CTD's between turns and army management screen

hi, my game crashes constantly after / during turn processing and after i transfered some units from one army to another using the army-management menue. it's my first game since the beta (which was very stable for me) and now my game starts crashing constantly after 30-60 minutes .

help would be most appreciated^^....i've uploaded the debug.err to mediafire [see "external link"]...hope it helps.
