Lightroom: Backup crash "Lightroom encountered an error when reading from its preview cache and needs to close"

When I do my regular backup, at the point when it is optimising catalogue it freezes with a message "Lightroom encountered an error when reading from its preview cache and needs to close". It then stops responding and has to be closed via task manager.
I have deleted all the preview caches and started again - no change. I also note that this does not happen with the other user of this PC/copy of Lightroom, where it works perfectly, regardless of whether the other user is logged on or not. The Forum has tried unsuccessfully to help.

Note: this problem also occurs when simply optimizing, even if not backing up.

Is problem with only one catalog, or all catalogs?
Is problem with only one user? (what if you create another test user - can he/she optimize?).

Stefan, what version is your operating system? And which version of Lightroom are you running?
