It seems that you are using an unsupported Plone version, in recent versions this expression is at line number 46. From the line numbers in your trace it may be 5.0.0, a four year old release with dozen of bugs fixed since this time.
if you are using an unsupported Plone version try to reproduce the problem in a test instance setup with the last version for this branch (that is, 5.0.8)
