Dear all,

when enabling "Publish Doxygen" option in the project settings the Doxygen Plugin crashes with java.lang.NullPointerException. The following backtrace is generated:

--snip--

It seems to me that the DoxygenDirectoryParser is fairly broken as there have been reported quiet a lot of NullPointerExceptions in the past. However, I think this is a new problem.

Please do not hesitate to contact me in case any further information regarding this issue is required.
