Comment 1

I suspect this is a near-dupe of bug 824297, and that (like that bug) this will be fixed by the patches in bug 812822.

Comment 2

[Daniel Holbert [:dholbert]]

Yup -- after I've applied the patches from bug 812822, this bug's testcase just fails the assertion from bug 399262 (which makes sense, since the testcase has a button w/ first-letter styling), and no other assertions.

(It fails that assertion in an unpatched build, too; presumably Jesse didn't mention it in comment 0 because it's expected & hence uninteresting for the purposes of this bug.)

Comment 3

[Daniel Holbert [:dholbert]]

Verified that this testcase's assertions are fixed in trunk now, now that bug 812822 has landed.  (aside from the assertion that's covered by bug 399262.)

Marking as dupe of bug 812822, and marking in-testsuite+ because this bug's testcase was included in that bug's crashtests push.
