>Description:
        I'm no expert in debugging things, sorry..
        
        I don't know exactly what happened, but I think this happened after the
        package had been partially removed, which iirc had failed, although
        this is sheer speculation.
        Please let me know whether you need additional information/files and
        SSH access if you think it helps.
        The package I tried to delete was gtk+2 in an attempt to perform an
        update.
>How-To-Repeat:
        If I knew exactly how I did this...
