Comment 15 for bug 122602

You guys probably already noticed this, but the duplicate bug #133565 contains an explanation of what probably is causing this for you, and why it is still a bug needing a fix even with the simple workaround.

In retrospect, I should have done that as a comment to this (thanks for pointing out the duplicate, Sebastien -- I don't know how I missed that), but it would be bad form to copy and paste it at this point.
