PSPP-BUG: [bug #44158] Crash when changing type of spreadsheet imported dataset

[Ben Pfaff]

Follow-up Comment #2, bug #44158 (project pspp):

It's related to changing the type of a variable that is still being pulled
from the original data source.  An experiment that shows that is, between
steps 2 and 3, use the scroll bar to scroll all the way to the bottom of the
data sheet.  This avoids the crash.
