"Invalid project description"

[jukzi]

After updating my platform workspace i found the following exception in my log:

org.eclipse.oomph.resources.backend.BackendException: org.eclipse.core.internal.resources.ResourceException: Invalid project description.
	at org.eclipse.oomph.resources.backend.BackendContainer.importIntoWorkspace(BackendContainer.java:158)

At least i would like to know which project the exception is complaining about in the exception message.
