QGIS crashes when opening a project having joined layers with spaces in names

Affected QGIS version: 3.0.0
Redmine category:relations

Steps to reproduce:
Add two layers to the project.
Add a space in layer name for one layer (i.e. "my layer").
Join this layer to another one, so that join has a space in it's name.
Save and close the project, open again - boom.

Should be an easy fix with using layer id's etc. instead of names with spaces.

I don't recall having that issue. Is the form tag appropriate or are we talking about a normal join?
