Mantid crashes when deleting group of workspaces

[Raquel Alvarez Banos]

To reproduce:

• Load ​https://github.com/mantidproject/mantid/blob/master/Test/AutoTestData/CSP78173.raw
• Delete one of the workspaces, for instance CSP78173_1
• Delete the group, i.e CSP78173, an unexpected exception is thrown:

WorkspaceGroup - index out of range. Requested=7, current size=7

• You can "Terminate", but if you "Continue" and try loading any dataset Mantid crashes
• On other datasets (for instance CSP79590.raw) the deletion of a single workspace in a group gives no errors.

I could not reproduce this crash. I tried removing one or more of the workspaces in the group, then remove the group. Nothing happens. Is any other step needed to make it crash?

There's a related issue about renaming workspaces in groups (#8050) that seems to be alive. And here's one more and somewhat related issue with grouping and renaming (#10514).

Hi Federico, thanks for having a look. I just repeated the steps in the description and it crashes for me. We can have a look at it when you are back.

This seems to be no longer an issue.
