[Chimera-users] Auto start and nogui option causing segmentation fault?

[Eric Pettersen]

Yes, could you submit a bug report (as outlined by Elaine below) and attach your preferences file?  If I set Model Panel to autostart, I get the “Starting extension 'Model Panel' failed” message, but no Python traceback.  So it’s some other tool that’s the problem and your preferences file will allow me to determine the culprit.  Your preferences file is /Users/danpf/.chimera/preferences.

Even though the problem seems to be with the nogui version, the menu approach is useful because it automatically includes Chimera version and platform information.  Either way, you could just paste in what you wrote in this message.  Since I’m no help in this case, reporting a bug is good to make sure that the right people see it (although some are currently away, so it may be few days before there is any response), and to get it into our bug-tracking system.

Problem is, I don't know which one is causing the seg fault, but I feel like it shouldn't be calling these gui options with the nogui options on anyway.  Once I started getting these errors I went to Favorites->add to favorites/toolbar->reset & save, and now I don't get the segfault. I do get a few other errors if I adda few back to the auto start / on toolbar options.
