----------------------+-----------------------
 If you install the buildbot from debian distro, and install buildbot nine
 with pip,

 then you got one buildbot eight in /usr and one buildbot nine in
 /usr/local

 This confused one user in the irc:

 maxime: can you paste the whole traceback?
 17:50           the error message is not one line, i'm sure
 17:53   maxime  sa2ajj: no it's not indeed, let me paste that somewhere
 17:55   sa2ajj  thanks
 17:56   maxime  sa2ajj: http://pastebin.com/KrptPjUR
 17:56   infobob http://paste.pound-python.org/[…]ftAVwx4L5gN1ksbc/
 (repasted for maxime)
 17:56   sa2ajj  infobob: thanks
 17:57   maxime  nice pastebin
 17:57   sa2ajj  interesting
 17:58           lissyx joined #buildbot
 17:58   sa2ajj  this looks like setup is not complete
 17:58           how did you install it?
 17:59           funnily the error is thrown from the code i developed :)
 17:59   maxime  sa2ajj: I used pip
 17:59           pip install buildbot==0.9.0b2
 18:00   sa2ajj  judging from the paths, 'sudo ...'
 18:00   maxime  yeah I jumped to using root for that command
 18:00   sa2ajj  can you run a couple of lines?
 18:00   maxime  sure
 18:01   sa2ajj  start python
 18:01           then 'import buildbot.plugins.db'
 18:01           'from pprint import pprint'
 18:01           'pprint(buildbot.plugins.db.info())'
 18:02   maxime  all the dictionnaries are empty, maybe you want the list ?
 18:03   sa2ajj  if they are empty, then corresponding changes to the
 "global" database was not done :(
 18:03           and that explains the error
 18:04           can you run (i assume you used sudo) 'sudo pip install
 --reinstall buildbot=0.9.0b2' and capture the output and then paste it
 18:04   maxime  Yup, gimme just a 2s, I don't use sudo
 18:04   sa2ajj  sure
 18:04           oh, not using sudo... :)
 18:05   maxime  I have pip 1.5.6 and I don't have a --reinstall options it
 would seem
 18:06   sa2ajj  wait, it might be my bad
 18:06   maxime  ah --force-reinstall ?
 18:06   sa2ajj  yeah, looks like it
 18:06   * sa2ajj        . o O (there are so many tools with _almost_ the
 same set of options)
 18:07   sa2ajj  but it might bring in more updates to other packages
 18:07           i'd suggest you play in a virtualenv sandbox
 18:07           (first)
 18:07   maxime  it's a test machine, so there's no worrying about trashing
 it

 18:08   infobob http://paste.pound-python.org/[…]zBpBSvd5Wl0bT0Gz/
 (repasted for maxime)
 18:08   maxime  nice bot :)
 18:08   sa2ajj  ah, ok :)
 18:09   maxime  the dicts are still empty :/
 18:10   sa2ajj  oh, you seem to have the old installation of buildbot in
 /usr/lib/python2.7/dist-packages and a new one in /usr/local/lib/python2.7
 /dist-packages
 18:10           this might lead to problems
 18:10   maxime  indeed !
