STR: 1) Open a new profile, and in Preferences, get it to load tabs from last time 2) Open up a bunch of tabs (this is optional, but helps make the bug more apparent) 3) Visit https://inventory.mozilla.org/en-US/user_systems or some other page that results in a modal dialog being spawned 4) Close the browser 5) Re-open the browser, and immediately focus another window before the browser finishes drawing 6) Once browser is opened, refocus browser window.

I assume this, like bug 939010, started on the trunk with the firefox-2013-11-18-09-41-34-mozilla-central nightly. It'd also be interesting to know its regression range on the ux branch.
