TimThumb issue with WordPress installed in Subdirectory...

With some hosting providers where instances of WP that were installed in a 
subdirectory were causing TimThumb to not be able to find the images. For 
example, the URL to the WP instance might look like this www.some-domain.com/wp/

When I did right-click "View Image" the error message displayed was:

The following error(s) occurred:

    Could not find the internal image you specified.
...

Yet, I can open the image directly in the browser using the image src URL, so I 
know the image is accessible.

My client contacted support at their host and this is how they were able to 
resolve it, here's a copy of the email:

"Ok, I enabled debug logging in your timthumb.php script and saw the following 
logged in our httpd error log:

   "Trying file as:
   /home/comhyuoes/webapps/dev2_
wp/wp/wp-content/uploads/2011/09/some-image.jpg"

So, it's looking for a 'wp' directory on the filesystem even though we've set 
the document root to /home/comhyuoes/webapps/dev2_wp.

I don't know why it's doing that, so I can't tell you how to properly fix it.

However, as an ugly workaround, I created a recursive 'wp' symlink inside of 
your app directory. With that in place, your thumbnails are now working."

What version of the product are you using? On what operating system?
TimThumb 2.8 (the latest to date)
WordPress 3.2.1

Any ideas what might be causing this??
