That was my suspicion too, regarding the original testcase/backtrace.   But comment 4 indicates that there are additional cases that are still broken.  (Note that comment 4 was about a day after bug 1804551 merged to mozilla-central; also, the [newer testcase](https://bugzilla.mozilla.org/attachment.cgi?id=9307472) doesn't use tables, so bug 1804551 wouldn't have helped there.)

Having said that: I can't repro any issues with the newer testcase.  I just tried loading a locally saved copy of it, in a debug build, with the attached `prefs.js`, and I don't hit any asserts or other issues.  Similarly: I can load that testcase in my debug build with a fresh profile with named-pages preffed on, with no issues.

Tyson, could you check again if we're still hitting this?  If so, a pernosco trace might be useful, since I'm having trouble repro'ing (and I suspect Emily may be as well)
