Fix exception handling to be python2.5 compatible The exception handling introduced in commit hg:494d2550: Display errors containing HTML with RejectRaw (issue2550847) contained the new style of exception handling that is not compatible with python2.5. Rework these exception handlers to use the old style to maintain compatibility with python2.5
