Redmine

Since a month i have issues when looking at the differences of an entire changeset. Note that watching differences of single files does work, this error only occurs when i click 'view differences' of changesets with multiple files.

This is what i found in the error log :

Rendering /home/redmine/webroot/public/500.html (500 Internal Server Error)

I think this doesn't occur on all repositories, just specific ones.
I am using trunk version of redmine with subversion. This subversion has a few svn:external svns defined.
Plugins i have installed :

• ezFAQ plugin
• code review plugin
• graphs plugin
• my widgets
• stuff to do
• schedules

This used to work but it suddenly stopped a while ago (a month or so...)
