That was more a note for other developers, we've broken something
between 0.99.0 and now either in tcp reassembly or in http's way to
use it, and we have to fix it. "HEAD" is the most current version in
the source code repository, and it fails as well as 0.99.6.

I've opened a bug report and attached the capture you gave.

http://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1851

You should add yourself to the CC: list of the bug so you'll be
notified whenever this is fixed.
