Summary

0006991: null pointer string operation in DirectoryClosedCallback

Description

Hi - I can repeatedly cause this crash on the mac (haven't tried other platforms yet.

What I do is open a file browser, then click on the + sign next to the / directory.

The problem generates the following in the console. The stack trace is pasted under Additional Information.
