NEW SOLUTION: There is new PDT Indigo bundle (3.0.2) which runs fine for me, out-of-the-box: http://code.google.com/p/zend-sdk/downloads/list

OLD SOLUTION (PDT 3.0.0):

Thank you Valentin, I could fix my Eclipse. For me it worked from your link like that:

1. Open https://hudson.eclipse.org/hudson/job/cbi-pdt-3.0-indigo/lastStableBuild/artifact/build/
2. Click on build number N*
3. Download pdt-Update-N*.zip
4. In Eclipse goto "Install New Software"
5. Create a new site with archive and choose the downloaded zip
6. Now PDT is updated from the downloaded zip

Link updated, thanks to Daff!

It is a bug in pdt that seems to be fixed: https://bugs.eclipse.org/bugs/show_bug.cgi?format=multiple&id=350139

(I know I'm answering pretty late, but it will help other people that come from google)

edit: how I fixed it on my computer (and I don't recommend you to do it like me):

Got the latest stable nightly build of pdt from https://hudson.eclipse.org/hudson/job/cbi-pdt-3.0-indigo/ which for me was: https://hudson.eclipse.org/hudson/job/cbi-pdt-3.0-indigo/166/artifact/build/N201107150957/

There seems to be a way to update eclipse plugins by using pdt-Update-.zip files explained here Getting Eclipse PDT nightly build from Hudson . I couldn't do that on my computer and I didn't had time to investigate why it didn't worked. I got the other zip file (pdt-SDK-.zip), removed the old plugins from eclipse library directory and put the new ones instead. It didn't work, the PHP perspective was nowhere to be found after that. So, I did a dirty hack: took org.eclipse.php.core_3.0.0.v201107150957.jar from the archive, removed the old one from the eclipse library directory (org.eclipse.php.core_3.0.0.v20110516-1100.jar in my case) and renamed the new one like the old one.

I am aware that this may break things and I don't recommend to other people to do that unless they do it as a temporary hackish fix :-)

I should have tried PDT 2 though...

Cleaning up my Available Software Sites preferences (Help>Install New Software), then updating Eclipse again (Help>Check for Updates) removed this error for me.

If anyone still looking for this, it just happened to me, and found out that closing "AMD gaming evolved" application fixed it.. If I open it again it happens, just close that if you have it and try
