Premiere Pro Crashes when Nudging Clip

Question

Premiere Pro is crashing (spinning pinwheel forever... go for lunch...45-60min, come back, force quite, "PPro has encountered a serious error") during simple tasks such as "nudging" a clip in the timeline or clicking with the "razor" tool.  This is destroying my productivity, any help appreciated.  This is hapening on 2 different machines linking to the same set of media.  Full system details below.
All Media is ProRes422(LT) stored on a AFP share drive.  Both systems are setup with media cache files on the local drive, Murcury Playback Engine (CUDA).
System 1:
System is running a fresh install of OS X 10.9.2 (as of Monday)
MacPro 5,1 dual 6-core 2.4GHz
48GB RAM
GTX570 2.5GB GPU (Driver: 8.24.9 310.40.25f01, CUDA: 5.5.47)
PPro CC 7.2.1(4)
Blackmagic Intensity Pro Card
Desktop Video 10.0
System 2:
iMac 13,2 i7 3.4GHz
OS X 10.9.2
16GB Ram
GTX 680MX 2GB (Driver: 8.24.9 310.40.25f01, CUDA: 5.5.47)
PPro CC 7.2.1(4)
Project files contain approx 13,000 assets and take upwards of 8 min to load all media.

Hi Scott.  The reason I made those suggestions was because I had the same problem once.  Nudging certain clips or moving audio keyframes resulted in an instant repeatable crash.  This was because I imported the XML with audio automation from an FCP7 project.  Stripping the audio keyframes cleared up the crashing issue.  I just had to remix the whole short film.     And Adobe also volunteered that they were seeing the same problems with stabilzation data.
I haven't seen much corruption on ProRes.  My experience has mostly been with JPEGs and Long-GOP video.
I haven't done much cutting off a network; mostly just transcoding or exporting.  But, no crashing ensued.  However, you could rule that out by copying some of your footage locally, and see if you get the same crashing.
Before Corrupt Clip Finder, I had a "search and destroy" method for finding clip corruption.  This goes back to my Avid days.  The routine in the same:  start isolating or taking half your media off line, and see if it still crashes.  Keep taking footage off until the crashing stops.  That tells you the corruption was in the last batch you took offline.
You can use the "Make Offline" feature in Pr without having to physically move anything.  So, another thing you could try is to take all your media off line, and see if you get crashes by nudging clips.  If so, that would implicate the project, and not the media.
