I just built Inkscape 0.46-devel and got the same result: Inkscape does not import any PDFs. It doesn't crash, but I just get a message "Failed to load the requested file <filename>". It does this even on PDFs that a clean 0.46 handles fine.
I did notice error output on the command line which I had overlooked before:
<filename.pdf>:1: parser error : Start tag expected, '<' not found
Sorry for the slow response on this ...
