Congratulations on the new release. Unfortunately, I get the following error when I attempt to use it.

Changing the locale settings for the document had no effect. Let me know if you require any further information.

@Fred.Kruse Any idea?

Managed to get it working. Reinstalled the previous version and attempted the upgrade again. Worked this time.

The error can occur, if you try to start the spell and grammar check dialog before LO has called the interface to check the first sentence. I added a bug fix for this in my last update today

The same error occurs on ubuntu 18.04lts along with Libreoffice Writer -7.x -, when I use the F7 function key. It works not too well using the Spell Check option.

Should we expect the release of version 5.1.1?

@Fred.Kruse can you point me to the commit id? I can make a 5.1.1 release then (or do you think the problem is extremely rare?)

I don’t know if the problem is rare or not. It occurs if someone is very fast and starts the dialog before any iteration in the background was done.
A new release at this point is not a good idea I think. There was some other changes and I’m working on some bug fixes right now. Could we shift it a few days?

By release, I mean a release based on 5.0 with only the bug fixes ported back to 5.0.

I mean 5.1, of course…

Yes, this is a good idea. But the change is hidden in a huge commit. Is it possible to get back to the code of 5.1. Only three lines are the solution to solves the bug:

        if(docLanguage == null) {
          docLanguage = getLanguage();

placed after:

        if (ltDialog != null) {

in file

It is placed in commit

There’s now version 5.1.1, could you confirm it’s okay? - it’s not linked yet, I’d link it once someone else has tested it

There was no feedback, but as the fix should be okay, I’ve now released and linked 5.1.1 (

5.1.2 has been released with a few fixes (see changes):
