Two NPEs for FlogHelper while startup

Message-ID <1321557659.3682.84.camel@datalus> 
Hi all,

attached is a logfile containing two exceptions while the plugin
FlogHelper is starting up. This randomly happens (but often) and I have
to shutdown my node, edit freenet.ini (remove the entry "FlogHelper"
from it) and re-add the plug-in.

I have a Debian Unstable AMD64 system with latest packages.

Regards,
Roland
