Cleaning up the error log...

7.0.0.8, but has been going on as long as I can recall...

I have stuff in my error log. Stuff I don't necessarily understand.
I've done a ton of tinkering; Java examples, RSE plugin examples,
tutorials - all sorts of stuff. My WDSCi is very stable and I figure
it's time to address the stuff that's hanging around in my error log.

Is there a way to turn on more intensive logging so I can find out what
component throws any given error, and then maybe I can figure out how to
clean it up? For instance:

Invalid preference page path: Browser Configurations
An exception stack trace is not available.

The .log file says
!ENTRY org.eclipse.ui 4 4 2009-03-06 09:13:53.953
!MESSAGE Invalid preference page path: Browser Configurations


No error number, no details. It's very difficult to STFW. I looked at
the Browser Configurations preference page and see no problems. I'm
using Flock; the path looks good, WDSC opens Flock when I call for help
in an RPG program. I just don't understand this (heck any) error I see
there.

Is it stupid to spend time to clear these things from occurring?
