Comment 12 for bug 1852183

Can confirm this suspected 'mutter' bad effect on calc 6.3.3 and mutter 3.34.1:

-happen with a calc spreadsheet when trying to copy/paste a formula cell:
 1) from a column's cell, right click to copy it
 2) select the first same column's cell to paste: get a graphic created (kind of image with 4 cells which are draggable and extendable) instead of the normal pasting result.
 3) deleting that graphic objet, then re-copying the original cell, finally the pasting is done as expected.

This has been seen for each copy/paste since calc 6.3.3 upgrade, not prior.

Also note that now LO is unable to load/open an ods file : after the Nov 11th upgrades; Does not get error from a terminal.
Only get a dialog box telling calc has silently crashed and will then try to recover the ods file: but there is no file listed to recover.
Indeed that ods file load/open as usual with version prior to Focal.
