When capturing traffic on a Windows 2003 Server virtual machine on top of
Parallels 4.0.3846 on MacOS 10.5.8, I received an error in Wireshark and on the
console:

09:49:40          Warn Dissector bug, protocol X509CE, in packet 1:
STATUS_ACCES
S_VIOLATION: dissector accessed an invalid memory address

See attachment for the offending packet by itself.  I would work on this myself
right now, but I'm in the middle of working on something else at work ;)
