--
When creating a capture filter using "ether host <MAC Address>", the parser
that decides whether the filter is well formed or not, crashes wireshark if two
colons are adjacent.

To recreate, goto Capture->Options
Put "ether host 00:00:00:00:00:00" in the "Capture Filter" box.
Delete any two 0's between colons until something like "ether host
00::00:00:00:00" results and Wireshark will crash.
