Just looked at the code in glib/gutils.c - can't find any mistake there,
also it tried it with an oversized entry and it worked fine for me.

However, I do remember that it attempted to dereference a NULL pointer when
it dumped core last time for me - unfortunately I already removed the core
file and the binary that was causing it and I'm now unable to reproduce it.
