Error without admin_toolbar

The mr fixes the exception.

Using the gin toolbar without admin_toolbar is not very satisfactionable, markup looks rather broken without icon classes, maybe add a dependency (could be a follow-up)?

Can you review this again with latest devs of Gin & Gin Toolbar?
Even without this change and without admin_toolbar it looks good to me.

Hi there. I'm getting the exact same error when upgrading from 1.0.0-beta14 to 1.0.0-beta15, but on a project that I've never installed contrib Admin Toolbar module (just the core Toolbar module).

Full error:

The website encountered an unexpected error. Please try again later.

@Ambient.Impact can you confirm that the provided patch will solve this for you?
=> https://git.drupalcode.org/project/gin_toolbar/-/merge_requests/7.patch

The patch does indeed fix the WSOD, but applying to both the stable release and the latest dev results in the same missing icons as in #4.

@Ambient.Impact => latest patch from MR (https://git.drupalcode.org/project/gin_toolbar/-/merge_requests/7.patch) should fix the issue now.

@saschaeggi That does appear to fix it, thanks!

Thanks y'all!

GIF link because I can't embed it here

Whoops. My bad. 😅

I noticed that this item wasn't included in the change log for the latest version, but the patch was failing to apply, so I assume the fix is in the released version hence the failing patch. If anyone else runs into this - just remove the patch as it's no longer needed.
