Comment (by jeremyhu@…):

 So the reason this workaround is successful is because you're getting an
 error even earlier.  The dlopen() is failing (due to the upgrade of ffmpeg
 making a dependency unavailable) and thus pthread_atfork() is never being
 called to register the atfork handler, and thus that atfork handler is not
 causing the crash on the child side of the fork because it is never
 called.

 > something changed between gegl 0.2.0_12 and 0.2.0_13 which matters

 No, it was just a revbump to force a rebuild with newer ffmpeg (r125491)

 > something changed in gegl's build environment recently which matters

 Nope.

 > not being able to load libavformat matters somehow (I suspect it's not
 loading because it refers to a different libavformat filename)

 Yes.  Not being able to load libavformat prevents pthread_atfork from
 registering the failing atfork handler.
