I'll file a bug report and upload the updated libwireshark.def file as a patch. I'm unfortunately not on expert on svn or branches, thanks for the documentation link. Hopefully if and when the bug / patch is integrated it will remain in future releases (at least that's what I would expect). I guess it's the wireshark release version that applies, i.e. if ok in 1.0.5 will work with all version above i.e. 1.0.6, 1.0.7 (one branch?) or 1.2.0 etc. (another branch?) provided functions are not removed etc. etc. I'll have a go next week. I must admit being able to "drop" a plugin into a release version and having it work is always nice. If you're lucky I might be able to contribute the plugin, but the internal approval process is unfortunately slow.

This is only true for releases in the same branch. SVN is simple in that respect: one incrementing revision number for everything (files and directories alike). So when an improvement is made in the development tree, it's not automatically available in a earlier release branch even though new maintenance releases in the release branch do have a higher SVN revision number. Have a look at the SVN documentation and http://wiki.wireshark.org/Development/ReleaseNumbers as well.
