On Mac this sequence does not crash but causes the main window to turn completely black as if the Qt opengl context is corrupted. Begin forwarded message: From: Tristan Croll Subject: Segmentation fault Date: November 30, 2016 at 6:23:15 AM PST To: Tom Goddard, Greg Couch, Conrad Huang Hi all, Just noting a reproducible segfault I came across by accident (in the Linux build). If I start ChimeraX, open the side view tool, immediately close that and then attempt to open the shell, it crashes with the below dump. Cheers, Tristan Fatal Python error: Segmentation fault Thread 0x00007faeb0fe9700 (most recent call first): File ""/home/tic20/apps/chimerax/lib/python3.5/site-packages/zmq/utils/garbage.py"", line 47 in run File ""/home/tic20/apps/chimerax/lib/python3.5/threading.py"", line 914 in _bootstrap_inner File ""/home/tic20/apps/chimerax/lib/python3.5/threading.py"", line 882 in _bootstrap Thread 0x00007faea5b98700 (most recent call first): File ""/home/tic20/apps/chimerax/lib/python3.5/site-packages/zmq/sugar/poll.py"", line 99 in poll File ""/home/tic20/apps/chimerax/lib/python3.5/site-packages/zmq/eventloop/ioloop.py"", line 122 in poll File ""/home/tic20/apps/chimerax/lib/python3.5/site-packages/tornado/ioloop.py"", line 862 in start File ""/home/tic20/apps/chimerax/lib/python3.5/site-packages/zmq/eventloop/ioloop.py"", line 177 in start File ""/home/tic20/apps/chimerax/lib/python3.5/site-packages/ipykernel/iostream.py"", line 72 in _thread_main File ""/home/tic20/apps/chimerax/lib/python3.5/threading.py"", line 862 in run File ""/home/tic20/apps/chimerax/lib/python3.5/threading.py"", line 914 in _bootstrap_inner File ""/home/tic20/apps/chimerax/lib/python3.5/threading.py"", line 882 in _bootstrap Current thread 0x00007faf9351f740 (most recent call first): File ""/home/tic20/apps/chimerax/lib/python3.5/site-packages/chimerax/core/ui/gui.py"", line 166 in event_loop File ""/home/tic20/apps/chimerax/lib/python3.5/site-packages/ChimeraX_main.py"", line 547 in init File ""/home/tic20/apps/chimerax/lib/python3.5/site-packages/ChimeraX_main.py"", line 638 in File ""/home/tic20/apps/chimerax/lib/python3.5/runpy.py"", line 85 in _run_code File ""/home/tic20/apps/chimerax/lib/python3.5/runpy.py"", line 170 in _run_module_as_main /home/tic20/bin/ChimeraX: line 7: 12680 Segmentation fault (core dumped) $CHIMERA_HOME/bin/ChimeraX $* " defect closed major Alpha Release Graphics fixed all ChimeraX
