-- Information about the crash:
Steps to reproduce:
 - right click the clock widget on the main panel and select "adjust date & time".
 - in the "adjust date & time" applet, (disable and) enable a time server.
 - click "apply" and perform authentication.
 - without waiting for a time server response, click "ok".

After clicking "ok" the message "Unable to authenticate/execute the action: 6," appears, followed by the crash dialog.

The crash can be reproduced every time.
