Just tried the resyntersizer plugin im using windows vista and used the pre compiled version of resyntersizer, there were some scripts to. After putting the files in my GIMP portable folders I tried the remove selection script and it ran.
Did you extract the resyntersizer plugin and its folder to "GIMP\App\gimp\lib\gimp\2.0\plug-ins "and the scripts to "GIMP\App\gimp\share\gimp\2.0\scripts" ... or the appropriate places for your operating system? thats the only thing off the top of my head I can think of as there both dependant on the file being in the speciafied place or resynthersizer wont be called up to run and may crash.
Although could be a script error, maybe there are some updated scripts? Im not too sure if it is still maintained as a plugin, it doesnt seem to be included in any gimp packages which is a shame could be a great plugin
