Bug in cchords_nrb.xml style rendering

Hi,

I'm trying to use the cchords_nrb.xml style but it's not working on Xyy7(#9). For example, I enter "Gmi7(#9)" or "C+7(#9)"(without quotes) and it does not convert to the style (remains in normal font). Other chord names seem to be correctly rendered, including "G7(#9)", "Gmi7", "C+7".

Version - 2.0.0 Rev 3c35a97
OS - Ubuntu 12.04

Thanks.
