Nautilus randomly slow and finally crashes

[Free Rage]

I migrated my laptop in 14.04.1 LTS (from a 12.04 partially upgraded in 13.10 for hardware support). Since then I have randomly very slow nautilus windows opening. When that happen, if a nautilus window is opened it become grey and the icons on the desktop are frozen the time for the new nautilus window to show up.

I thought problem solve by editing .gtk-bookmarks in home directory witch contained some old reference to unavailable samba shares [edit : that file (.gtk-bookmarks) is no longer used, so that was why it was refering to old shares. The new one ~/.config/gtk-3.0/bookmarks has no reference to unavailable shares]. But the problem arise again and I get some random crashes.

I tried to launch nautilus from command line but no message.

Note that I had to upgrade samba due to the bug https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1257186

The same problem can happen even when I try to open the printers window.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.
