The stack trace here seems corrupted but the errors.ubuntu.com report that is linking to this bug report [1] shows a proper stack trace.
This indicates the problem is when a warning dialog pops up on startup due to either the home directory or desktop directory not existing. Some following code then assumes this dialog is a file browser window and hits an exception. I tried to reproduce this locally by deleting my Desktop folder / replacing it with a file but then it just reverts to using the home directory. The error reports don't give an indication on what users are doing to trigger this. I can reproduce the crash by modifying nautilus to show the dialog always on startup.
