Here is what I can do: I can stop the crashing when another application
(whether it maintains clipboard history or not) pastes the BMP format and
LibreOffice can't allocate enough memory for the image.

However, I cannot solve the temporary hanging when another application pastes
every single format. That is one big downside of clipboard history
applications: they are very convenient but if you copy a large amount of data
(and 80000 cells is a lot of data), most clipboard history applications use up
a lot of memory very quickly. After all, Calc advertises that the copied cell
data can be pasted in 7 different formats and some of those are image formats. 

I am guessing that this high memory usage is a big contributing factor in the
system crashes you have seen in tdf#160644. Don't know how configurable your
clipboard history applications are, but hopefully they have some options for
pruning their clipboard history after memory usage for the history exceeds some
amount.

Even better is if your clipboard history applications can be configured to
ignore formats that you rarely use. From what I've seen, by default clipboard
history applications paste every format available.
