We saw this before at bug 643732 . Despite what I said on that bug, I recall that I did take a quick glance and couldn’t find an immediate obvious leak, but the context-reading code is a little gross.

Sorry for the reassignment. We weren't checking previous owners before assigning, but now we do. Shouldn't happen again.
