I experienced the same bug too and was hoping noone used that version before I got to fix it :-p It is the default search providers that have been overwritten with an URL containing the first barcode you searched for. To fix this you just have to update to the newest version of the plugin and remove the config file by running this command in terminal: Code: rm /home/user/.config/mbarcode/webrequest-plugin.conf The next time you run the application everything should be as it is supposed to.
rm /home/user/.config/mbarcode/webrequest-plugin.conf
