Attempting to run a JS callback during garbage collection. This is most likely caused by destroying a Clutter actor or GTK widget with ::destroy signal connected, or using the destroy(), , dispose(), or remove() vfuncs.
Earlier today, polari spammed my system journal with approximately 2 million lines of:
Attempting to run a JS callback during garbage collection. This is most likely caused by destroying a Clutter actor or GTK widget with ::destroy signal connected, or using the destroy(), dispose(), or remove() vfuncs. Because it would crash the application, it has been blocked. The offending callback was SourceFunc().
I'm not sure how to reproduce this. I only noticed it in my journal after the spam had already finished.
