From your previous emails, I'm assuming this is on Ubuntu.

2.5.x now has the DOCSIS dissector built in; it's probably somehow finding a DOCSIS plugin.

If you've installed it (as I'm guessing might be the case, given that you're not explicitly running "./wireshark" or 
"run/wireshark" or "build/run/wireshark"), then, if you already had an installed version, and the new version was 
installed on top of it, the install process probably left behind the old plugin.  Check whether there's a "docsis.so" 
under the installation directory for plugins and, if so, remove it.
