I do not believe this is related to 496530, since bidimap appears in this back trace, and not there.

I cannot reproduce by merely outputting a lot of text to stdout (on current konsole, but not many changes in this area for the last two years). If you can reproduce it regularly, it is possible to try to debug it.
