Segfault after Capture Frame using NVidia Linux Graphics Debugger

I'm attempting to capture a frame of a simple Unity project using the Linux Graphics Debugger. The Linux Graphics Debugger is able to launch the application properly, and show some metrics.

Once I trigger "Capture Frame", I get a warning that reads:

"Detected Unsupported operations that may cause errors or a crash during capture. First seen unsupported operation: glDisableClientState (Classic attributes are not supported)"

Continuing past the warning indeed crashes. The log shows:

"5045 Segmentation fault (core dumped) DISPLAY=:0 LD_PRELOAD=a/b/c/libNvidia_gfx_debugger.so /a/b/c/abc.x86_64"

Ubuntu 14.04 Quadro 3100M GPU w/ driver 352 Unity 5.1.3 application built for x86_64

Any idea why this might be happening?
