totem-video-thumbnailer crashes when copying or moving files to USB drive

[Alejandro Serrano]

When copying or moving files to an external USB drive, the thumbnailer crashes.
However, if I refresh the window, the thumbnail is created correctly.
My guess is that there's some sort of race condition between copying and reading the file for thumbnailing.
