[mythtv] Current CVS compile problem

[Robert Chastain]

Current CVS compile I'm getting this error. Anyone else seeing this? I was
running the previous nights CVS with no problem.

tv_rec.cpp: In member function `int TVRec::GetChannelValue(const QString&,
Channel*, const QString&)':
tv_rec.cpp:969: no matching function for call to `QVariant::isNull()'

Thanks,
kelsey
