Crash while running EQSANS from the HFIR_Reduction GUI

[Brett Tully]

System crashes with the following errors when running EQSANS from the HFIR_Reduction GUI in 1.1.9517 RHEL 5. Both situations should throw an error, but I wouldn't expect them to crash the GUI; when run via the automatically generated script in each case, the error is handled as you would expect.

Crash 1: Error printed to Bash command line -> "An error occurred while running EQSANSTransmission. See results log for details."

• Scattering data file: "...Test/Data/EQSANS_1466_event.nxs"
• Click reduce
• SOLVED by: using beam finder with data file: "...Test/Data/EQSANS_1466_event.nxs"

Crash 2: Error printed to Bash command line -> "An error occurred while running LoadSNSEventNexus. See results log for details."

• Scattering data file: "...Test/Data/SANS2D/SANS2D00002500.nxs"
• Click reduce
• No solution found, but when the same process is run from a script, the error is handled and Mantid does not crash.

I understand that these are incorrect data files for this interface, but we should handle the errors without crashing

This ticket was created a while ago. Please tell the user to try with the latest version of MantidPlot. Crash 1 it now fixed (leaving the beam center to 0,0 will NOT produce meaningful results, but the reduction won't crash). Crash 2 is clear from the log in MantidPlot. EQSANS reduction needs event data. I may add a message to that effect.

(In [10437]) Specify that we need event data. Re #2450

Please verify and reopen the ticket as needed.

These two examples no longer crash Mantid in 11111
