Bug: Calculate folder size sometimes crashes app

[timowers]

Description

Turning 'Calculate folder size' on the very first time caused an error dialog, but is unrepeatable.

Steps To Reproduce

Open Settings.
Folders tab.
Calculate folder sizes - turn on and error dialog popped up.
Close program. Repeat. No error is generated.

Steps to fix

The error, not crash, that happened seems to have been a one time only event. The only exception in the log does not appear to be associated with this error.

[hecksmosis]

What did the error say?

[timowers]

Unfortunately I cannot remember the full error text other than the title which was something like 'An error has occurred ' and cannot find a log of the error. Other than the log file would it have been recorded elsewhere and which files could be deleted or reset in order to make program behave as if its a first time use scenario and possibly being able to recreate the error?
