Hoverzoom crashing on some links/thumbnails

[GoogleCodeExporter]

I'm having crashes when hovering over certain links or thumbnails on Reddit. 
Disabling hoverzoom makes these crashes go away.

Example page:

https://pay.reddit.com/r/nottheonion/comments/2b7gol/new_san_francisco_billboard
_warns_workers_theyll/

If I hover over the thumbnail, I immediately get the "He's dead, Jim!" tab 
crash page.

Interesting -- if I view the page via 'http://reddit.com' instead of the 
https:// version, the crash goes away.

This is the last thing to show in the console before the crash on the SSL 
version of the page:

The page at 
'https://pay.reddit.com/r/nottheonion/comments/2b7gol/new_san_francisco_billboar
d_warns_workers_theyll/' was loaded over HTTPS, but displayed insecure content 
from 
'http://pando.com/2014/07/17/new-san-francisco-billboard-warns-workers-theyll-be
-replaced-by-ipads-if-they-demand-a-fair-wage/': this content should also be 
loaded over HTTPS.

I've reproduced this so far on both Windows and Linux versions of Chrome. Don't 
have the Windows version number handy at the moment, but the Linux Chrome 
version is 37.0.2062.20 beta (64-bit).

Fresh example since the previous repro no longer works (the source article 
vanished):

https://pay.reddit.com/r/videos/comments/2d3vss/hand_swallowing_cars_and_traffic
_100/

Hover over video thumbnail and the tab crashes.
