Expected Behavior

I expected that it'd be possible to enter text within a custom browser dock.

Current Behavior

A segmentation fault occurs when I attempt to enter text into a custom browser dock;

(obs:161196): Pango-CRITICAL **: 11:05:16.947: pango_layout_new: assertion 'context != NULL' failed

Thread 1 "obs" received signal SIGSEGV, Segmentation fault.

Steps to Reproduce

1. Add a custom browser dock, e.g.:
   • Dock Name: test
   • URL: https://www.duckduckgo.com.
2. Select 'Close'.
3. Attempt to type anything into the search bar in the browser dock.

Anything else we should know?

NOTE: It does occasionally work when I run it with a debugger attached - so this seems like, maybe, something racy?

NOTE:

• libgtk-3 at 3.24.41
• libpango at 1.52.1

Here's the GDB where output - didn't help me much.

Thanks; I did look for an existing issue, but perhaps I used the wrong keywords.
