Dear sugar-devel, (and Tomeu and Simon in particular),

I decided to spend a few hours this evening investigating the state of
rainbow+sugar.

My current results are based on tests performed in a Debian Squeeze chroot
constructed according to the procedures I wrote down at

   http://wiki.sugarlabs.org/go/Development_Team/Chroot

Today, these procedures wound up installing

   education-desktop-sugar 0.837
   python-sugar-0.84 0.84.1-1
   python-sugar-toolkit-0.84 0.84.4-3

and a variety of other things.

I then installed rainbow according to the source code installation instructions
at

   http://wiki.laptop.org/go/Rainbow/Installation_Instructions

and installed the sugar and sugar-toolkit patches:

   curl 'http://dev.laptop.org/git/users/mstone/sugar/patch/?id=71df9fadd59ea5cc08a414f5d25a0135395533e5' | patch /usr/share/pyshared/jarabe/view/service.py
   curl 'http://dev.laptop.org/git/users/mstone/sugar-toolkit/patch/?id=a65c8d2148ba5028437114049027e594238f2ed8' | patch /usr/share/pyshared/sugar/activity/activityfactory.py

that Sascha and I wrote a few months ago.

Then I ran

   touch /etc/olpc-security

to tell sugar to try to use rainbow.

Then, after commenting out a few lines in /usr/bin/rainbow-sugarize, (notably,
handling of XAUTHORITY, .sugar/config, and TMPDIR), I ran into the following
persistent activity-launch failure:

(See attached log for full details; the interesting bit is excerpted below.)

-------------------------------------------------------------------------------

Based on this traceback and a quick round of Googling, it seems likely to me
that at least one of gconf or orbit is assuming that human operators have only
one uid.

Hence two questions:

   1. Do you know anything about such an assumption?

   2. Are more bleeding-edge versions of Sugar still using gconf-over-orbit?

Regards,

Michael
