Does not start after upgrade to 3.7.0 with pip3 due to faulty schema

[sphh]

After upgrading from 3.6.3 to 3.7.0 Guake does not start anymore.

I intalled Guake 3.6.3 with
sudo pip3 install guake
and consequently updated it with
sudo pip3 install --upgrade guake

Expected behavior

Guake 3.7.0 should start.

Actual behavior

I get the following output, when I start guake from the terminal:

Guake not running, starting it
Loading Gnome schema from: /usr/local/lib/python3.6/dist-packages/guake/data

(guake:23924): GLib-GIO-ERROR **: 23:19:04.112: Settings schema 'guake.general' does not contain a key named 'display-tab-names'

I use Linux Mint 19.3 and Python3.6.

Well, I downloaded the new org.guake.gschema.xml schema, saved it in an empty directory, cd'ed into this directory and compiled it with glib-compile-schemas, resulting in a file named gschemas.compiled. Then I could move the compiled schema into /usr/local/lib/python3.6/dist-packages/guake/data (use you own Python version!) replacing the existing schema and change ownership with sudo chown root.staff gschemas.compiled. Now Guake starts.

Would be great, if the PyPi package will get an updated compiled schema …

Thankt @sphh. That worked for me too. Using debian 10.3. But actually I had already gschemas.compiled in guake/data. I had to replace existing gschemas.compiled

[sphh]

@kirillsafin, you are right: There exists a schema which has to be replaced. I updated my post #1718 (comment).

[sphh]

I believe #1621 is related.

Did some testing, figured out that if there is an existing schema, guake will not generate a new one. Only attempts to generate if there is no schema, patch coming to attempt a fix.

I've opened a pull request with a potential fix. From the pull request's branch, you can run make wheel to create a wheel file in a /dist directory, then pip install the wheel. If this resolves/doesn't resolve the problem, confirmation in the open pull request or here would be appreciated.
