In the process of migrating remaining bugs to the new severity system, the severity for this bug cannot be automatically determined. Please retriage this bug using the new severity system.

Comment 3

[Daniel Holbert [:dholbert]]

No assertions anymore in a recent debug build (possibly because the testcase uses <div style="display: -moz-popup;"></div> which doesn't do anything these days).

--> WORKSFORME, and I'll add a crashtest.

Attachment: Bug 1145950: Add crashtest for this (fixed) bug. r?#layout

I'm adding this as a traditional crashtest rather than a WPT crashtest since it
uses -moz-popup which is non-standard (which also doesn't do anything in Gecko
at this point, actually). Probably better to avoid cluttering the shared WPT
directory with crashtests that were poking holes in gecko-specific legacy
features.
