Why does installing an extension take this much memory?

I tried to install the Gammalecte extension (https://www.dicollecte.org/grammalecte/) and Libre Office didn’t response. So I check the Activity Monitor of MacOS and LibreOffice is using more than 15Go of RAM !

I had to kill the processus. Is it normal ? What should I do ?

Did you report it to the developer?

I cannot reproduce this problem with LO 5.2.1.1 on Windows 7. The extension installs and works fine.

Ok I found the problem, it’s with Mac OS and Libre Office.

You can’t double click on a extension to install it, you have to open the Extension Manager panel and click the Add button.
