CounterStrike Source Crashes when hit with flying object

[mr_x408]

Hey everyone, when im playing a source engine game everything seems to run smoothly until an object comes flying at me, eg. (in garrys mod someone decides to try and drop a big container on me and when it hits me the game crashes) this happens in css and zombie master source too. could anyone tell me how to fix this problem,
thanks in advance
i am running wine 1.1.26 under ubuntu 8.10
