This looks like the same crash as bug 395651 -- did we not actually fix it? Was it fixed and then something regressed it? (note this test is now checked into the testsuite -- bug 395651 comment 7) Assigning to jst who fixed the old version. Feel free to farm it out, but with the test in the tree we're going to want a fix sooner than later.

May have to push this to 184.108.40.206 (code-freeze for .11 is May 6) but would at least like this looked at given the checked in testcase.

Johnny, we really don't want to lose this for 1.9.0. Can you investigate for 22.214.171.124?
Looks a lot like bug 490513.

This doesn't crash using Firefox 2 and isn't wanted there.
Whiteboard: [sg:critical?] → [sg:critical?] post 1.8-branch
This was a regression from the branch port of bug 439206 (as, it seems, was bug 490513). If you look at the patch there, it clearly addressed an incompleteness of the patch for bug 421576 -- which only landed on mozilla-central and was intentionally not backported to 190, introducing this [sg:critical?] bug. Oops. I filed bug 497204 to reorganize and consolidate this code, because if four different people can write and review incorrect patches for this code (particularly security-critical code like encoding/decoding code), it clearly needs it. Well, at least we picked up another point on Acid3 in this snafu (the original reason I investigated why the fix worked, incidentally).
