I'm working on packaging thunar-svn-plugin for Ubuntu and Debian, but one of the largest hangups is the GTK code embedded in the plugin causes it to FTBFS if you don't use 2.6.0 specifically. It seems possible to disable the embedded code via a preprocessor macro, but that also fails to work. Is it possible for the GTK code to be removed, or at least get the preprocess macro working?
The gtk code is removed and the preprocess macro is enabled to get a replacement widget. This code is fixed so the preprocess macro is working. Committed in r6802.
