I can recreate this so I will find when it breaks.
A tip though Geoff, if you jump back e.g 10 commits at a time find when it works, then jump halfway between that and the previous, repeat, you would have probably found it in less than 6 attempts ;)
I'm having the exact same issues. I'm running PMS on a synology NAS and just upgraded to the newest release (0.9.8.10.215) from 0.9.7.28.33.
I might have missed something, but are you saying that it appears to be a problem connected to the version of Plex Media Server and PlexConnect? I apologize if that sounds condescending, and I promise you it is not intended that way, I really want to ask if that is your theory?
It appears there is a bug in some of the newer versions of PlexConnect in the list view for large movies collections, the workaround is to use grid view.
Geoff could you grab the latest version of PlexConnect, the Movie List problem should hopefully be fixed now, please let me know if it is, Thanks.
I was about to reply with "I got the one that was updated 5 hours ago" but realized that is a month in PlexConnect update years, and so I pulled up the commit from 2 hours ago and it is working. Thank you so much for committing to solving this. As a non-programmer I am unsure what I am looking at when I pull up: http://goo.gl/pl0kSY. What was changed/causing the problem?
