Title: Protect against nil method in BacktraceLineNormalizer.

Recently upgraded errbit from a fairly old version, and had a failure in the ExtractBacktraces migration. This change fixed it - aside from that the upgrade was 100% painless, thanks guys!

Let me know if this seems problematic in any way.
