Bug 339501: NPE in Call Hierarchy.

[*] CHQueries.java 1.20 http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.cdt-core/org.eclipse.cdt.ui/src/org/eclipse/cdt/internal/ui/callhierarchy/CHQueries.java?root=Tools_Project&r1=1.19&r2=1.20

I simply fixed the NPE. Note, that the call-hierarchy does not work for functions found in the binaries.
