This bug caught my attention as I couldn't imagine what kind of system
would cause it but it was easy enough to reproduce on my ubuntu system
(and fix). The trunk patch below prevents a memory fault but doesn't
do anything useful with the error (except inform the user that
LD_LIBRARY_PATH is absurdly long). The error could also occur if the
_MEIPASS2 environment variable was particularly long. I'd be happy to
test another patch for this bug.
