Comment 1

[Robert Strong (they/them - no direct email)]

btw: I have verified that backing out the patch from bug 484764 fixes this bug

Comment 2

[Peter Van der Beken [:peterv]]

Hmm, this is a harmless ASSERTION failure. sObjectClass hasn't been initialized at that point.

Comment 3

[Peter Van der Beken [:peterv]]

Marking this duplicate of bug 500846 because that one has a patch.
