[apport] totem-video-thumbnailer crashed with SIGSEGV

Binary package hint: totem

Description of the problem:
While downloading an mp4 video to the desktop (while also watching it within totem) apport popped up and mentioned that the thumbnailer had crashed.

Steps to reproduce:
1. Download http://media1.podtech.net/download.php?file=media/2007/03/PID_010739/Podtech_Joel_Spolsky_interview.mp4 to ~/Desktop .

Expected results:
Thumbnailing to only occur when file is completely downloaded/timestamp stops changing frequently. No crash to occur when thumbnailing.

Actual results:
Attempts at thumbnailing can take place before the file is fully downloaded. Thumbnailing sometimes crashes.

How reproducible is this bug:
I have yet to attempt to reproduce although a second apport crash report window for gnome-thumbnailer popped up while I was filing this bug (the site this mp4 is downloading from seems to limit the speed to 40Kbytes/s).
