    IPCError on U1 at control panel

    Running Kubuntu 12.10, ubuntuone-control-panel-qt v4.0.0-0ubuntu1. Any mouse click on the control panel results in "IPCError" although the control panel appears to be functioning correctly after closing the error window.

    Terminal output:

    this is bug https://bugs.launchpad.net/ubuntuone-client/+bug/936942

    sorry offtopic, but your may remove warning
    Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.

    command in Terminal
    mkdir -p ~/.config/fontconfig
    mv ~/.fonts.conf ~/.config/fontconfig/fonts.conf

    Re: IPCError on U1 at control panel

    Perhaps this workaround

    Also in OT suggestions, simply deleting the offending line9 is also an option. If you are yet to try Infinality fonts, I strongly suggest giving them a shot...
