[ BUILD # : 200807170007 ]
[ JDK VERSION : 1.6.0_07 ]

When running the PHP Project with existing source wizard, it often
stops in the middle of the process.
And then produces an exception report and the new project doesn't
appear on the Project Explorer.

Turned out it did create the new PHP project intended, but we need to
open it through the main menu (File - Open Project).
After that, then it also appear on the Project Explorer.

The steps to reproduce this error:
1. Run the New PHP Project with existing source wizard
2. On Step 3, click the Finish button.
3. Then on the left, a progress bar (Creating index file) is
displayed.
4. It's progressing until 80% and then it stops.
5. When we click Finish or Cancel button, this error message comes
up.
6. The new project didn't appear on the Project Explorer.
