No, it simply suggests that your copy of the package was compiled using 
the -g flag (standard for R in most cases, and inherited by packages with 
source code). Did you install from source, or a binary? Have you tried 
running R -d gdb to determine where the problem occurred? Have you 
contacted the package maintainer, best with a copy of the object (save()) 
and a script to reproduce the error?
