Comment 13 for bug 949171

This is a real bug - i.e., scrolling doesn't work. I'm not sure if it's a gwibber problem or a scrollbar problem, but we cannot say that scrolling not working is "invalid" as a bug report. Nor does the fact that the issues are being worked on make a bug report invalid.

Marking the bug as invalid increases that chances that a basic feature will ship in an unacceptable state. If you are trying to reflect that the bug is in Gwibber, then that status should be marked as confirmed. If you are trying to reflect that there is on going work on scroll bars that will fix this issue, then the status should be in progress or confirmed.
