It seems that aMule-cvs-20050302 at least has different behaviour with the aMule.tmpl and webserver directories.
I run with a modified webserver template with darker colours and different images. Since I upgraded to this CVS version, these are all *ignored* by amuleweb. The webinterface now runs with the default template and images, and even if I remove aMule.tmpl and the webserver subdirectory, the webinterface is still set to the default.
Probably I have to replace the template and images in the source, and recompile amuleweb. I'll give that a try and report
