From the looks of it, mViewManager was ok, until

Processing pending restyles on the _parent_ can wipe out the presshell. 
Processing pending restyles on mFrameConstructor should have no effect on |this|.

Although, processing pending restyles can create XBL bindings, hence run arbitrary script, hence kill |this|.

It sounds like comment 2 and comment 3 may be extremely concise summaries of bugs that deserve [wanted-1.9] or blocking1.9+, but there's not enough information in this bug for such consideration, and the bug that appears to be describe here seems too obscure to merit either of those on its own.  Please file those as separate bugs if you still understand what you meant; you're welcome to renominate those.

Flags: blocking1.9? → blocking1.9-

The issue described in comment 3 is fixed by the patch for bug 267833.  So no need for a separate bug on that.
