Renaming current folder via location button leads to criticals

Version information

4.19.3git-166ab0f1

Steps to reproduce

1. Enable the Shortcuts sidepane and switch to Buttons Style for the location selector
2. Rename the current (non empty) folder via its location button context menu

Current behavior

It may take some attempts, but eventually Thunar will generate some criticals (or will segfault when debug flags are set).

Expected outcome

No criticals or segfault.
