This seems to be not MySQL-specific, but related to libstdc++ as shipped in Ubuntu. Or it could be from a libstdc++ -related PPA, in which case it isn't a bug. Whichever way, let's move it away from the MySQL packaging and closer to the package with the problem, if indeed it is even a problem in Ubuntu.
