# would mean that you are running a buggy version of DBD::SQLite     #
# known to randomly segfault on errors. Even if you have the latest  #
# CPAN module version, the system sqlite3 dynamic library might have #
# been compiled against an older buggy sqlite3 dev library (oddly    #
# DBD::SQLite will prefer the system library against the one bundled #
# with it). You are strongly advised to resolve this issue before    #

# If this happens to you (this text is the last thing you see), and  #
