Description:
Shortly after opening a Calc document, when I attempt to EDIT (COPY) the content of a single cell, the app crashes. This happens roughly 5 mins after the document has been opened and after several similar edits have been made. Immediately after the app crashes, a "Recovery" window pops up and the file can be recovered intact. This is happening consistently since the last version update. 

(I am using an Apple Macbook Air) 

Steps to Reproduce:
1.Open existing Calc document
2.Make some routine format edits (which occur)
3.Attempt to make another format edit by copying the content of one cell.

Actual Results:
The app crashes. It only crashes when attempting to COPY the content of a cell. Then a Recovery window opens automatically showing the file name that crashes. By clicking on the file name, the file re-opens at the same place prior to the crash. 

Expected Results:
The recovered file works fine until the same crash occurs again... about 5 mins later. 


Reproducible: Always


User Profile Reset: No

Additional Info:
It should not crash when attempting to COPY the content of any cell in the spreadsheet.
