Comment(by mikeperry):

 FYI, the relevant code is invokeDragSessionWithImage() in external-app-
 blocker.js.

 I do have a Mac. If it crashes on me enough times, I might be motivated to
 get to this soon... But the stack trace is in the middle of nowhere, so
 most likely I'll just be banging on the JS code blindly.

 It's quite likely there is an underlying Firefox XPCOM bug on Mac
 triggering our woes here.. Which means I'm going to need to install
 Xcode+gdb and set up my Mac for Firefox development to fix this one... Not
 something I'm looking forward to.
