I've been digging a little deeper on this issue. First, I look for other binaries in /usr/bin that dynamically link to either libgtk or libgdk (at least for starters). In short, I found other binaries that exhibit the same issue. I may have narrowed it down to possibly /lib/x86_64-linux-gnu/libgdk-3.so.0. In addition to firefox and thunar, I can recreate the crash in font-manager and gucharmap. All four of these binaries suck in libgdk-3.so.0 dynamically. A diff of the ldd output for these binaries shows other potential culprits but thus far, libgdk-3.0.so.0 might be a likely candidate to investigate further. Interestingly, pcmanfm uses the old libgdk-x11-2.0.so.0 and does not crash.
To recap, I can create the crash at will by dragging some draggable object in any of these applications. Simply dragging it a pixel or two is all it takes. I ran thunar, font-manager and gucharmap with $GDK_SYNCHRONIZE set to 1 and the --gdk-debug=all parameter. I'll upload the respective output.
