Loading this testcase makes Firefox (debug) crash with
Nightlies crash too, but with a slightly different stack trace.

I can reproduce on the Firefox 2 branch, too, so nominating for blocking1.8.1.
Too late for this type of thing, should fix for 220.127.116.11
Usual problem -- the XBL constructor is run while the frame tree is not yet done being constructed, it does some stuff, said stuff triggers a select event firing, which removes the node from the tree (and destroys its frames). Then we unwind and attempt to insert said deleted frames into the tree, dereference 0xdddddddd (in debug builds, or random memory in opt builds), and crash.
Does this happen in 1.8.0.x as well?
Jonas: Can you take a look at this?
By bzs description I don't think we should try to fix this one particular crash since there's a bigger general issue that can cause many different types of crashes. I.e. that we run XBL ctors at unsafe times. I'll try to look in to that issue as i'm whacking XBL and nsCSSFrameCtor interaction in general.
does the "whacking XBL and nsCSSFrameCtor interaction in general" work have bugs or a spec to help tracking the work and its possible impact on fixing this one? be good to add those links here.
Marking blocking for now. Hopefully the fix for 267833 will fix this one.
Doesn't crash now (probably due to the patch in bug 267833).
