On Mac OS-X El Capitain, after upgrading from XQuartz 2.7.8 to 2.7.9 the software tools from the KARMA package (http://www.atnf.csiro.au/computing/software/karma/) now seg fault when opened.

I tried to upgrade to 2.7.10beta, to check if that helped. It did not, but at least provided the following error:

Downgrading to 2.7.8 fixed the issue, so it must be something thats changed since then.
