gvfsd-smb crashed with SIGSEGV in g_vfs_job_run()

[Edson T. Marques]

I encountered a problem when detaching a tab from a terminal to a separate window and then detaching another tab to a newly created window. Terminal application crashes every time. To reproduce this problem create a terminal window with 3 tabs and then detach one to a separate window followed by moving another tab to a newly created window.

I did the upgrade that was available earlier today (4/29/2013), and meanwhile, was accessing several sessions terminal server with rdesktop. After the end of the upgrade I just closed the program updater window and after a few seconds, this crash appeared.

Happened twice.

[Runar Ingebrigtsen (ringe)]

For me, this crash happened as follows:
1. I opened a Nautilus window, wrote an smb:// address in the address field.
2. Logged in, browsed the files
3. Closed the open Nautilus window
4. Re-opened Nautilus
5. Clicked the "unmount" icon for the smb:// mount
6. This crash.

This appears to be purely because I'm disconnecting a share or usb drive and therefore there's no listing to display after the disconnect?

Pretty much the same as Runar's problem, surely eveyone must get this or is it just a version thing?
