import gwibber.lib gives couchdb errors

Binary package hint: lernid

I installed lernid (apt-get install lernid). I have Recommends and Suggests off in apt.conf. When I try to run it, I get this:

% lernid
Traceback (most recent call last):

This might be a gwibber bug rather than lernid, since it seems to be doing an "import gwibber.lib" that causes the problem.
Looks like either gwibber or lernid is trying to run COUCH_EXE, without checking whether it's installed, or requiring that it be installed.

As you can see in the dependencies.txt file you attached (or apport did) both couch-db and desktopcouch are listed so I doubt it it a problem with dependencies. I don't know who's at fault here but I'm pretty sure it's not Lernid.

[Akkana Peck (akkzilla)]

You're right. It's a problem with couch, not lernid.

The error listed above is happening because /etc was in my path (probably a holdover from some earlier system; I don't think there's any reason I still need /etc in my path on modern Linux, but a lot of sysadmin programs used to live there.) /usr/lib/python2.6/dist-packages/desktopcouch/local_files.py line 43 does this:
    for x in os.environ['PATH'].split(':'):
        if os.path.exists(os.path.join(x, 'couchdb')):
            COUCH_EXE = os.path.join(x, 'couchdb')
and since there's both /usr/bin/couchdb and /etc/couchdb, and there's no break in the loop, couch matches the last match rather than the first one and ends up trying to execute /etc/couchdb.

But if I remove /etc from my path, and try "import gwibber.lib" in python, I just get an error a few lines farther in the same file:

gnomekeyring.IOError

That's inside a try clause, but the only exceptions handled are gnomekeyring.NoMatchError and gnomekeyring.CancelledError:, not gnomekeyring.IOError.

This is on a system that's not running a gnome desktop, so it may be assuming some gnome keyring service that isn't running, and not checking for the error in that case.
