It has happened again on the same install of Jython 2.5.2rc3 on 64bit Linux,
previously on build 6, now on build 12:

http://events.open-bio.org:8010/builders/Linux%2064%20-%20Jython%202.5.2/builds/12/steps/shell/logs/stdio

Again, repeating the build made the error go away - but the load on the
machine would have been different etc.
