Awesome! That would be version 0.14.x which fortunately is what's in
Debian stable. Makes me wonder why the Debain Maintainer deemed it
necessary to backport 0.16.x to stable-backports. Apparently Debian
Maintainers consider 0.14.x ancient and unsupported, a bug report
against it ("high CPU usage on Raspbian") was rejected. Go figure.
But why are you breaking compatibility with your LTS version in the
latest HEAD? Or is that no longer the case as you seem to indicate

The problem was verified with version 0.16.3 by me personally. That
version was released upstream about two months ago. So the constant
claims of "fixed long time ago" become kind of irritating after a
while. I'd be glad to hear the incompatibility between your LTS version
and 0.15.x forward has been fixed somewhere in HEAD and I'd look into
getting that patch accepted into Debian and Ubuntu.

Sure. I'm not complaining. I simply was unable to use the software
productively and moved on. Such is sometimes the life for an LTS user.
You then revisit the issue when you are on the next LTS.
It is kind of comical that in your first mail you sent me you seemed to
propagate the notion of "users of a distro should not bother upstream
with bug reports, they should be dealt with at the distro level". I
think that's actually true for the first few stages of bug triage.

I understand. And that's where I think ideally, Distros and especially
the maintainers (Debian) or bug triagers (Ubuntu) have a positive role
to help upstream IMO. For one, distros provide you with many eyeballs
and corner cases. But the bug triage needs filtering to make sure
upstream gets quality feedback.
BUT, above problem is with your LTS version! So, if you are serious
about it, you ought to not pull the card of "this software is too old
for us to look into (lack of manpower)".

AFAICS, that's still missing the packaging information. Where can I see
for example the debian/control file of version 0.14.19-1 as published at
http://xpra.org/dists/trusty/main/binary-i386/ in binary form?
http://xpra.org/src/xpra-0.14.19.tar.bz2 unsurprisingly doesn't have
it. Even in svn I can't find the relevant tags, but it's well possible
I'm looking in the wrong place (http://xpra.org/svn/Xpra/tags/v0.14.x/
is what I tried). GPL requires the full source (that includes meta-data
such as packaging) be distributed alongside the binaries.
