Nullpointerexception when browsing svn

[ste...@stefant.org]

Hello,

Here is my setup: Multiple repositories, one of them has a non-public
subdirectory in the root of the repository (the first directory). The
repository is accessed using http. Tomcat is 5.5, sventon 2.0.2.
When I access the repository with sventon (url /svn/<repos>/list) the
html output terminates after the first checkbox in the file list, and
I get two nullpointer-exceptions in the sventon.log.

I am not quite sure if the access restriction causes the exceptions,
but thats the only thing that is different from the other
repositories, which work. It makes no difference if I use anonymous
authentification or user-authentification (without specifying a
username/pw in the properties-file).

Exceptions are:
