Tomcat (libreplan) NullPointerException (Error 500)

Hello,

I am running libreplan on my arch server. Can't post my question there, as the sign-up requires captcha, but it's broken -.-
I keep getting this error in various sections of the website. Everything seems to work despite the error, but it's really annoying. Any ideas?

cat libreplan-error.log
ERROR [03-August 13:33:02] [http-8080-6] org.libreplan.web.error.PageForErrorOnEvent  - Unknown exception: java.lang.NullPointerException.
