includeTopic and PDF issue

I'm working on a large document that I've split into sections using the includeTopic tag. However, I notice that once I use an includeTopic tag, that PDFs can no longer be generated (it tries to open an html page rather than a pdf.) Is there a workaround to prevent this behavior? Also, is there an xwiki bugs page to see if items like this have been submitted prior? Thanks in advance, Vern
