Orange crashing on startup

[borondics]

Orange crashes on startup if I simply start it from the command line.
If I use a style it works fine.
orange-canvas --style=cde is OK.

Orange version

3.6.0.dev0+425ff7a

Expected behavior

Start Orange Canvas

Actual behavior

RecursionError: maximum recursion depth exceeded

Steps to reproduce the behavior

Simply Start Orange

Additional info (worksheets, data, screenshots, ...)

This is the full terminal output:

I cannot duplicate the error. However at one point I already made this change in a 'related' project. I do not remember why though (if I saw the recursion or on a hunch?), but it is worth a try.

Can you please checkout the proposed changeset in #2636 by running

git fetch https://github.com/biolab/orange3 pull/2636/head:pull-2636
git checkout pull-2636

in your local checkout

[borondics]

Aleš, It fixed the problem... Will you migrate it in the main branch? Do I just check out the main and update later? Feri
