title: XQuartz 2.7.8 crashes on Mac OSX Yosemite 10.10.2
body: <p>I've been running XQuartz for years on several macs, but ver since I upgraded my iMac to Yosemite (now at 10.10.2) I can't get XQuartz to run at all.  I've tried re-installing and upgrading XQuartz, even tried the 2.7.8_beta3, but the result is always the same - the upgrade/install itself succeeds, but when I try to launch it, it crashes.  Below I've included the beginning of the error report; I've been messing around with DYLD_LIBRARY_PATH, it's possible that I've just made matters worse.  Can anyone suggest a way to trouble-shoot this?
  Thanks - Ed</p>
