#8 Syntax problem

[Erwin Komen]

The following is a valid Penn Treebank sequence: (A w1 (B w2)).
However, this situation raises a warning from CorpusSearch (WARNING! extra label: ...).
It occurs for instance in YCOE\psd\CoBoeth.o2.psd on lines 12261, 12263, 22746.
Other search programs like TregEx do handle this situation without problems.
Could something be done about this?
