Title: Interesting problem with tshark

I have a set of related plugins that work fine in wireshark proper, but fail to work under tshark. They all worked fine as of ethereal 10.13 (the last ethereal that I used).

The base dissector watches for TCP/IP connections, parses off a network layer and the protocol number of the nested protocol. It has a registered table for subdissectors. This plugin works fine in tshark - I get summary lines from that base dissector, and in verbose mode it shows me the correct protocol numbers and packet lengths. However, none of the sub-dissectors, that work fine in wireshark, appear to run in tshark.

I currently use tshark for regression testing on trace files. Currently I have to disable all of these tests because of the seeming problem with tshark.

I have scanned the subversion log since the 0.99.1pre1 release and the bugzilla listings, but didn't immediately see anything related to the problem. Any hints?
