reproducible with 061201

steps:
1. create package with scoped class diagram
2. add template class with name 'A'
3. add derivation classifier 'A<B>'
4. create package with scoped sequence diagram
5. add lifeline
6. try to find 'A<B>' in edit control autocompletion for classifiers
there is no A<B>
7. try to find 'A<B>' in drop down for 'Representing Classifier' property
absent
8. add lifeline 'SAMPLE:CL'
9. drag the derivation classifier from tree to the diagram
lifeline ':A<B>' is created
10. check this lifeline 'Representing Classifier' property
property doesn't show correct value, in my case it shows 'int' but may be it may
show another value if there is no 'int' in project
