deluge crashes after a while

[vg o'hara]

hello, Deluge crashes after a while, what should be the reason for this?

normally i put the computer for downloading and leave home and when i come back it has worked for 10mins and see deluge had closed itself. or even when you are working on the computer, deluge again closes itself. right now it happened again, where i had started the deluge before i was writing these, and now it has already gone..!

i use xfce 4.8 xubuntu

thanks.
