Editting a page with Gutenberg result in a white page

[djvanroest]

I've WP 4.9.8 with the latest Gutenburg 3.7.0. When adding pages with Gutenberg editor active, at some point, I'm not abble to edit the created pages anymore. It results in (almost) a white page. I still see te nav bar at the left.

My console tells me dat value prop in color objects passed by withColors HOC is deprecated and will be removed from Gutenberg in 3.9. But thats a warning. I get two errors: TypeError: Cannot read property 'models' of undefined and Uncaught (in promise) TypeError: Cannot read property 'models' of undefined.

Console output:

load-scripts.php?c=1&load[]=jquery-core,jquery-migrate,utils,jquery-ui-core,jquery-ui-widget,underscore&ver=4.9.8:9 JQMIGRATE: Migrate is installed, version 1.4.1
index.js?ver=1535811221:1 value prop in color objects passed by withColors HOC is deprecated and will be removed from Gutenberg in 3.9. Please use `color` prop passed in the object instead. Note: This is a global warning, shown regardless of whether value prop is used.

Hi @djvanroest, welcome to WordPress Trac! Thank you for testing Gutenberg.

Until Gutenberg is merged into core, we're tracking its issues on GitHub: ​https://github.com/WordPress/gutenberg.

If there's still an issue, could you please report it there? Thanks again!
