Maybe I should fix that. Lemme see what that would take.
Uhoh, looks like something a lot worse managed to sneak into master. While test-driving that tip-rt build, I couldn't help noticing that evolution is going mad, chewing cpu and being useless enough that I couldn't reply to you. Unfortunately, it ain't my tip-rt tree, nor is it virgin tip, the evilness is present in virgin master, but not in 5.10 stable. Hohum, a hunting I shall go I suppose.
