Comment 2

[Daniel Holbert [:dholbert]]

As in bug 1499268, the testcase-snapshot shows that we used the wrong font here (a "serif" font, probably the default font, rather than the requested sans-serif webfont).

jfkthame, do you know if anything changed recently that might've introduced a font loading race condition?  This isn't a class of bugs that I recall seeing much at all, and it's a bit suspicious that we had two instances (in two different quite-old tests) in a ~30 hour period.  (those two instances being this bug & bug 1499268)

Comment 4

[Daniel Holbert [:dholbert]]

(Also notable: the two logs we have so far (one log on this bug, one log on bug 1499268) are both Windows 7, so this might be some bizarre [but new?] win7 issue like bug 1392106.)

Comment 5

[Daniel Holbert [:dholbert]]

(I ended up filing bug 1499459 as a general issue for these, so I've moved the needinfo to that bug, so we can have the discussion/diagnosis in a more general spot rather than on a specific instance of the failure.)
