pcmanfm crashed with SIGSEGV in fm_file_info_is_dir()

[Eliah Kagan]

pcmanfm crashed on a Lubuntu Quantal i386 system, in a Lubuntu desktop session. I don't believe I was actively using it at the time. My guess is that the crash was on session logout, but I am not sure of that. I don't know what triggered the crash or how to reproduce it. This somewhat resembles expired bug 780385, but I'm not sure if they're related.
