Exporting a .product for macosx results in a NullPointerException

I am trying to build a product using Eclipse RCP for multiple systems (linux gtk/x86, macosx cocoa/x86_64, win32 win32/x86), but I keep on getting a NullPointerException when exporting specifically to macosx. I am running Linux, and the linux and win32 builds export fine, and without issues.

I am running Eclipse 3.6.2 (Helios) and have installed all the nescessary libraries for the project (it runs fine). As well, I am able to run it fine under OSX. I have also installed the nescessary delta to enable the multi-platform RCP export.

The following is the error log from the export. Note that the temp directory doesn't exist under .metadata/.plugins/org.eclipse.pde.core/ after the export errors out.

Any help would be much appreciated. I killed a whole day on this, and got nowhere, and me excelent google skills haven't brought me back anything.

I had the same problem a while ago and I think I solved it by removing the branding images (Bug 292327). This bug was resolved a while ago (2009) but it might be a point to start from..
