But those were fixed, so it's some similar, but different problem. Unfortunately, to debug this I need either to be able to reproduce this on my system (unlikely, since I'm guessing GTK triggers that bug on your system), or I need you to run a debugging session described in https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27668#89 and show the results. But since you cannot trigger the problem at will, it sounds impractical. So it sounds like we are stuck, sorry.
