(Core :: Layout, defect)

Description

[Marcia Knous [:marcia]]

Seen while looking at trunk crash stats. Crashes started showing up using the 2011122000 build. https://crash-stats.mozilla.com/report/list?signature=nsTypedSelection::selectFrames%28nsPresContext*,%20nsIRange*,%20bool%29 

Possible regression range: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=d75ebb37080e&tochange=2afd7ae68e8b. Seems to be one layout related bug in that range: Bug 672013

One comment: Browsing the Apple App Store website. Bombed!. Will work on trying to reproduce now.
