+Subject: [PATCH] GContextSpecificGroup: detach sources
+
+GContextSpecificGroup has been somewhat broken for a rather long time:
+when we remove the last reference on an object held in the group, we try
+to clean up the source, but fail to actually remove it from the
+mainloop.
+
+We will soon stop emitting signals on the source (due to it having been
+removed from the hash table) but any "in flight" signals will still be
+delivered on the source, which continues to exist.  This is a problem if
+the event is being delivered just as the object is being destroyed.
+
+This also means that we leave the source attached to the mainloop
+forever (and next time will create a new one)...
+
+This is demonstrated with the GtkAppChooser dialog which writes an
+update to the mimeapps.list file just as it is closing, triggering the
+app info monitor to fire just as it is being destroyed.
+
+Karl Tomlinson correctly analysed the problem and proposed this fix.
