Comment 10 for bug 911461

I cannot reproduce the problem wit Ubuntu 11.10 and lp:mixxx.

The attached patch forces to handle the config file as UTF-8. This patch is needed for Windows to store characters that are not in the local latin. On Ubuntu Qt should handle text files as UTF-8 as default already. So this might not be the problem but is worth a try.

I have notice something else with the attached log:

Note: The qDebug function prints has a bug with decoding QString to UTF-8.

On my system the output looks like that:
Debug: [Main]: BrowseFeature::onLazyChildExpandation QVariant(QString, "Enlaces rápidos") QVariant(QString, "::mixxx_quick_lnk_node::")
Debug: [Main]: BrowseFeature::activateChild QVariant(QString, "Biblioteca Mixxx") QVariant(QString, "/home/daniel/Música/")

Your log looks like that:
Debug: [Main]: BrowseFeature::onLazyChildExpandation QVariant(QString, "Enlaces rápidos") QVariant(QString, "::mixxx_quick_lnk_node::")
Debug: [Main]: BrowseFeature::activateChild QVariant(QString, "Biblioteca Mixxx") QVariant(QString, "/media/Datos/Mis Documentos/Mi música/")

Both Strings "Enlaces rápidos" and "Música" are double UTF-8 encoded in your case. But your screenshot shows "Enlaces rápidos" correct, just as in my case. I guess that the double UTF-8 encoding was happen on the way to launchpad.

Can you provide your ~/.mixxx/mixxx.cfg file?
