Another possibility is that something else happens to use the port (17500) that the Dropbox Lan Sync dissector registers for. There doesn't appear to be any validation in the dissector that the protocol is the expected one.

What did the protocol tree show for the packet in question? Can you post the capture somewhere public, e.g. CloudShark, Google Drive or (oh the irony) Dropbox?

Another system on your network ( is probably using Dropbox. If that is your address, you should probably check if Dropbox was installed as an "add-on" for another piece of software.
