[defect] Legacy sensitivity file loading causes Mantid to crash with out clear error message

[glass-ships]

Problem Description:

Got some error in loading legacy NeXus files into Mantid. The files may or may not work depend on different scans, though there is no obvious difference on the files themselves.

PR34141 works around the issue, but needs some work to make it ready to merge.

Steps to Reproduce:

Mantid will just quit without any clear error message on the 'wrong' ones. Any clue on what is going on? Or any suggestions on how to debug on Mantid will be greatly appreciated.

The file which is not working with Mantid is:

/HFIR/CG3/IPTS-18679/shared/Exp440/s6v/All/ConvertedXML/CG3_044000120001.nxs.h5

The one that is working is:

/HFIR/CG3/IPTS-18679/shared/Exp440/s6v/All/ConvertedXML/CG3_044000120003.nxs.h5

Mantid tries to load the file and flashes some message then crash with the "report error" message box

Investigation/Analysis Results:

If I turn off loading logs, I can load the file

In a script add LoadLogs=False to the Load or LoadEventNexus calls will also avoid the crash
