shares-admin crashes when trying to add a folder

[Morpheus]

Control panel - shared folders. I unlock the app (using the unlock button), click the "add" button to add a folder to the shared folders section. The program simply closes, no apport crash message.

If I run 'shares-admin' from the cli, it also simply closes at the same stage with a "segmentation fault (core dumped)" message.

I'm still new to bug reporting, bare with me !

You say it no longer effects ubuntu-mate, yet I still have this problem
after havibg installed latest updates today. Am I missing something ?

Status changed to 'Confirmed' because the bug affects multiple users.
