I think what he means by "load the log files" to Open the Log File Viewer and Then select File, Open and then browse to /var/log and then select a single log file. Repeat as many times as there are logs you want to view.
I've tried this and the files opened seem persistent - that is they are reopened after the Log Viewer is closed and re-launched.
So, I've got a fix, but this probably is a bug. Most newbies would not know how to do this. As an experienced user (3 years with Mint, 3 with Ubuntu before), it isn't exactly obvious. It is also a deviation from all the preceding releases where the Log Viewer worked out of the box with most logs visible by default.
