When the file is not in the repo, I get an Exception when I call IFileRevision.getStorage:

org.eclipse.core.internal.resources.ResourceException: Path not in commit 046198cf5f21e5a63e8ec0ecde2ef3fe21db2eae 1254268023 ----sp.
	at org.eclipse.egit.core.internal.storage.CommitFileRevision.locateBlobObjectId(CommitFileRevision.java:121)
	at org.eclipse.egit.core.internal.storage.CommitFileRevision.getStorage(CommitFileRevision.java:71)
	at org.eclipse.team.internal.ui.history.FileRevisionTypedElement.fetchContents(FileRevisionTypedElement.java:64)

How can I check in advance if the file is in the commit?
