Description:
The same file can be clicked twice from the open menu, thus opening twice in the same LibreOffice instance, and when the two file instances come up, system will crash.

Steps to Reproduce:
1.From the LibreOffice open menu, click open the same file twice.
2.
3.

Actual Results:
System crashes when the two file instances come up.

Expected Results:
The system should only open the same file once: after a file is opened, any subsequent click on the menu should take no action.


Reproducible: Always


User Profile Reset: No



Additional Info:
Kindly bear in mind there are some slow computers out there, and when a file is clicked in the open menu, sometimes there looks no response due to whatever reason:
- system running slowly due to other running tasks, or
- LibreOffice does responding slowly somehow.

It will be natural the user will click the file again to ensure the opening command is issued, and this will cause trouble.
