Sorry for not posting this to the description of the patch file. The attached
patch fixes a bug in the moving average calculation which could make wireshark
crash.

The bug can be reproduced by following these steps:
1) start a capture
2) open the io graph
3) create a filter which filters out all packets, e.g. "tcp.port==0"
4) set smooth to some value other than "No filter"
5) crash.

The reason for the bug was a division-by-zero error.
