small patch

I upgraded my system today and it installed a new version of the libstdc++ library. Showeq started seg faulting whenever I zoned into a zone that I had zone filters set up for.

I tracked it down and fixed it, but I'm not really a C++ dev. I'd appreciate other eyes checking off on it.

Code:
