LibreOffice Writer mail merge wizard needs Base to operate but there's no message

[mspanc]

Ubuntu comes without LibreOffice Base by default.

In LibreOffice Writer, in Mail Merge wizard, at step 3, there's a window that allows you to select data sources. It does not work (basically, after selecting a file you cannot proceed) unless Base is installed.

Expected behaviour:

LibreOffice prompting about installing Base, in the same way it does when you want to run Bibliography Wizard
