New description:

 1. Select the parcel in the attached screenshot (Autogenerated_SDF_ID =
 8149)
  2. Create a buffer from this selection with default settings

 Expect: A buffer to be created around the selected feature

 Got: The stock message for a C++ null pointer de-reference:

 Problem:\nThe application encountered a problem and could not finish the
 operation you just requested properly.\n\nSolution:\nIf it\'s the first
 time you met this problem, try again or restart the application / session;
 otherwise, describe the steps to reproduce this problem to the server
 administrator for suggestions.

 Modifying buffer.php to show the stack trace reveals it to be at:

 - MgGeometry_Buffer() line 14619 file MgApi_wrap.cpp

 Observed in the AJAX viewer (.net and PHP) in both MGOS 2.2 and trunk.

 Note that the un-bufferable feature in question is not the same feature
 that had tripped up FDO in the past (http://trac.osgeo.org/fdo/ticket/382)
