Compiling the following file with latex modern in kile:
###
\documentclass[a4paper,10pt]{article}


\begin{document}
 asd

\newpage

asdf
\end{document}
##
results in a dvi file called test.dvi.
If this file is located in a directory like /home/kdedev/kile-projects/test# (i.e. with a # in the name) the forwardDVI call from kile results in the okular command line
###
okular --unique 'file:/home/kdedev/kile-projects/test#1.dvi#src:17 ./1.tex'
###
and than okular complains 
okular(9881)/okular (app) Okular::Document::openDocument: No plugin for mimetype '"application/x-zerosize"'.
and does not open the file.

If this is a kile bug I'd happily fix kile :)

Thanks,
