Pilot6, thank you for providing the requested information. I also got the 'Erase disk' problem, but this is a different problem, covered in: https://bugs.launchpad.net/ubuntu/+source/udisks/+bug/1092195
The patch for this report was targeting only the fact that when one attempted to make a bootable media via clicking the button Make Startup Disk, it would crash during this process. ** Description changed: [Impact] usb-creator is unable to create usb sticks with Ubuntu on it for lots of people, due to this crash. [Test Case] - We never came up with a reliable test case for creating the crash in this bug report. There are reports of being able to recreate it by using usb-creator on an amd64 system to create and i386 iso with persistence. However, I think the best way to verify the fix is to check the errors bucket and ensure that the -proposed versions of the package do not appear on that page. + What is expected to happen is when one plug in a freshly FAT32 formatted drive (example hardware this is reproducible on, but not limited to): + Bus 004 Device 002: ID 1058:1130 Western Digital Technologies, Inc. + + and clicks button Make Startup Disk, it doesn't crash. What happens is + when it prompts for the sudo password, it crashes during this or after + accepting the password. + + We never came up with a reliable test case for creating the crash in + this bug report.

Errors bucket: https://errors.ubuntu.com/bucket/?id=/usr/bin/usb-creator-gtk:11:_dbus_watch_invalidate:free_watches:socket_disconnect:_dbus_transport_disconnect:_dbus_transport_disconnect and possibly this bucket https://errors.ubuntu.com/problem/2a6909bd90bfe27a333e310be9e091055841a810 - To reproduce: Fairly reliably reproducible with ubuntu-12.10-desktop-i386.iso or raring-desktop-i386.iso and choosing persitence on a 12.10/raring amd64 system.

It seems to be that NULL is passed to _dbus_watch_invalidate. And that function does not assert it's input. In the past this caused to crash tomboy (bug #1043887), evalution-data-server (bug #852342) and possible other software (e.g. https://bugzilla.redhat.com/show_bug.cgi?id=553601 ). I'd like to open dbus bug and fix that function in dbus to be more resilient.
