I have Mediawiki installation went from 1.17 through 1.18 RC1 and to 1.18 - no problems.
But another Mediawiki has had some problems going direct from 1.17 to 1.18 - I took out Recaptcha and now see this:
*Fatal error*: Cannot redeclare wfprofilein() (previously declared in /xxxxxxxx/public_html/includes/profiler/Profiler.php:14) in */xxxxx/public_html/includes/ProfilerStub.php* on line *25*
Not sure why...

Sounds like you upgraded MediaWiki by extracting 1.18 on top of 1.17 instead of extracting 1.18 to a new directory then moving the config and other stuff to the new directory. And have an old StartProfiler.php.
includes/ProfilerStub.php was moved to includes/profiler/Profiler.php and includes/profiler/ProfilerStub.php in 1.18
Basically what it looks like is happening is that you have a includes/ProfilerStub.php file from 1.17 and includes/profiler/ from 1.18. Because your StartProfiler.php likely uses the old method of a require_once (instead of autoloading as I believe we now do) MediaWiki is loading the 1.18 profiler code from includes/profiler/Profiler.php and then when it require your StartProfiler.php that old require_once is requiring the old 1.17 code from includes/ProfilerStub.php causing a fatal error as the old code tries to redefine the same method.
If you don't need the profiler I recommend you delete your StartProfiler.php. If you do you should probably delete the require_once line. You'd also probably be better off clearing out all the outdated files of 1.17 code that were left behind since you extracted 1.18 over top of 1.17. Though the easiest way to do that is to just re-untar 1.18 in another directory, and move your actual LocalSettings, extensions, images/, etc... to there.
