emule, started by wine, crashes sometimes

I have a notebook (amd sempron 3000+, 512 ram) whit Ubuntu Edgy Eft inside. Sometimes, when I'm using Emule, windows version, whit the help of wine, it crash. The system remains stable and the only thing that happens is that emule closes.

I use the shell to have a output. Sorry for my English, I'm Italian
