Recurrent error on Ubuntu 14.04 and OS X 10.10

[gtms]

With the Repl server on, I run the command zotelo-set-collection on a *.tex file.
Both on Ubuntu 14.04 and on OS X 10.10, with Emacs Prelude, I get the following error message on the *moz-command-output* buffer:

TypeError: Components.classes['@zotero.org/Zotero;1'] is undefined

The *message* buffer reports, with the variable zotelo-verbose set to t:

zotelo message [Mon Feb 23 13:14:15 2015]
Moz-command finished

zotelo message [Mon Feb 23 13:14:15 2015]
Moz-command finished

zotelo message [Mon Feb 23 13:14:15 2015]
Collections:
!!! TypeError: Components.classes['@zotero.org/Zotero;1'] is undefined

Could you please provide me guidance to debug this error?

Hi. I cannot reproduce this with ubuntu 14.10, firefox 34 and zotero 4.0.26.1.

Looks like your zotero is not found.

Above those messages, there is also the javascript code which is run in firefox. Something like this:

var zotelo_filename=('/home/vspinu/works/reviews/Alternat_bayes_rule_2015/review.bib');
var zotelo_id = 211;
var zotelo_translator_id = '9cb70025-a888-4a29-a210-93ec52da40d4';
var zotelo_prefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components.interfaces.nsIPrefService).getBranch('extensions.zotero.');
var zotelo_file = Components.classes['@mozilla.org/file/local;1'].createInstance(Components.interfaces.nsILocalFile);
var zotelo_recColl = zotelo_prefs.getBoolPref('recursiveCollections');
zotelo_file.initWithPath(zotelo_filename);
//split
var zotelo_zotero = Components.classes['@zotero.org/Zotero;1'].getService(Components.interfaces.nsISupports).wrappedJSObject;
var zotelo_collection = true;
var zotelo_translator = new zotelo_zotero.Translate('export');
if (zotelo_id != 0){ //not all collections
    zotelo_collection = zotelo_zotero.Collections.get(zotelo_id);
    zotelo_translator.setCollection(zotelo_collection);
};
//split
if(zotelo_collection){
    zotelo_translator.setLocation(zotelo_file);
    zotelo_translator.setTranslator(zotelo_translator_id);
    zotelo_prefs.setBoolPref('recursiveCollections', true);
    zotelo_translator.translate();
    zotelo_prefs.setBoolPref('recursiveCollections', zotelo_recColl);
    zotelo_out=':MozOK:';
}else{
    zotelo_out='Collection with the id ' + zotelo_id + ' does not exist.';
};
//split
zotelo_out;

You should be able to run it in mozrepl or firefox console (firebug) and see what's causing your error.
