It is perhaps worth mentioning that while this bug looks superficially like bug 819116, the stack traces reveal that they are different crashes.

@Michal Hruby
Why have this and bug 825673 been made duplicates of private bug 820572? Does that private bug have a better stack trace? Has work already begun on it? (If not, would it be suitable to mark the private bug and its duplicates as duplicates of some public bug instead?)

Sorry, I forgot to make the other bug public, but yes the stacktrace is more useful there.
