I get the following two warnings when starting octave in GUI mode without the
package `libQt5Sql5-sqlite` installed:

% octave --gui

>Could not copy help collection to temporary
>file. Search capabilities may be affected.
>Cannot load sqlite database driver.

>Could not setup the data required for the
>documentation viewer. Only help texts in
>the Console Widget will be available.

These are gone after installing `libQt5Sql5-sqlite`. Maybe this package should
be
marked required or at least recommended/suggested for the `octave` package?

Thanks and cheers
