I've just upgraded ikiwiki from version 1.45 to 1.49, using my own Ubuntu Gutsy
backport. Now I can't rebuild all my wiki pages. Both methods of rebuilding pages fail:

    $ sudo ikiwiki-mass-rebuild 
    Processing /home/ptecza/path/to/ikiwiki.setup as user ptecza ...
    failed to set egid 1000 4 20 24 25 29 30 44 46 104 109 110 119 1000 (got back 1000 1000 119 110 109 104 46 44 30 29 25 24 20 4) at /usr/sbin/ikiwiki-mass-rebuild line 38, <$list> line 13.
    Processing /home/ptecza/path/to/ikiwiki.setup as user ptecza failed with code 65280

    $ ikiwiki --setup ikiwiki.setup

    terminate called after throwing an instance of 'Xapian::InvalidArgumentError'
    Aborted

I've installed all needed packages for new search engine and added path
to `omega` binary in my `ikiwiki.setup` file.

Any ideas how to fix that problem? --[[Paweł|ptecza]]
