[SOLVED] microsoft visual c++ runtime library runtime error

This is the crash i get pretty often while i'm playing. It depends more or less of the map played. I noticed the worst is when playing newtonian nightmare.
I try to look for this issus on the net but found nothing really helpful.
I also wondered if i was alone in this case...
Sometime i even get BSoD, but if it happens again i'll post a new thread for that as long as i don't know if problems are related...

Do you get any more specific information from the error?

What version of Windows are you using?

i'm using xp
and the error message says:

title:microsoft visual c++ runtime library
runtime error!
program <path>\xonotic.exe
abnormal termination

that's all information i see about the error

well i think this is somehow related to my old graphical card. this is just a feeling, no solid proof though...
