I received this bug report against Heimdal. For the full report, including the
first stack trace I omitted, see http://bugs.debian.org/561850.

My initial thought was this might be another case of library symbols
conflicting from different shared libraries. If I had to gamble, I would say
that is not the case though.

Unfortunately I have never used smartcard support, so am not familiar with how
it works.
