Segfault relating to InstrumentView and possibly masking?

[Janik Zikovsky]

Steps to reproduce:

• LoadEventNexus('CNCS_7860_event.nxs', 'cncs')
• Right-click workspace and choose instrument view
• Go to mask tab
• Mask out some detectors
• Run LoadEventNexus with the same file and output workspace name again.
• While LoadEventNexus, AFTER it has deleted the original workspace but BEFORE it has finished and replaced the workspace in the mantid workspace list, CLICK on where the workspace USED to be.
  • I sometimes have to do the steps twice, but I didn't get it to crash without clicking on that spot.
• Segfault.

Weird, I know. This is on Ubuntu 11.04

Fix if fast and safe, otherwise move to iteration 31

Observed segfault on rhel5 but not on Windows7 or Ubuntu10.04. Without clicking it happens 100% on the 3rd run of LoadEventNexus. I don't have a quick solution.

The last commit message was lost. I removed display lists from the renderers in Geometry. It is done to remove opengl commands from destructors.

[Michael Reuter]

I tried this on Mac, RHEL6 and Windows 7 and I can't get it to crash via the mechanism described, so it must be fixed.
