Big Problem with asaving

For some reason everytime someone asaves anything the mud crashes and there is always an error in an area file (a large portion of it disappears) and I have to load a backup. We can't do anything building wise at all. I ran the mud through gdb and got this :

Can anyone give me any advice?

You need to do another step, type "bt" in gdb to do a backtrace. That will show what is calling strlen. Probably a null pointer, but you need to know the context.
