The "Open in dictionary" feature does not work for me as well. When I select text and call the menu action, simply nothing happens (not even a message or console output stating that there was an error). I have both mstardict (configured with a few working dictionaries) and fbreader installed, and mstardict is running fine in standalone mode. mstardict integration is enabled in fbreader's configuration. (This is about fbreader on the n900) Is this supposed to work?
