Problem with projecting ntuple data into 1D histos with variable bin widths..

Has anyone attempted to project ntuple data into a histogram
with non-equal bin widths?

I find that using

ntuple->Draw("a>>histid","","");
or
ntuple->Project("histid","a","","");

work just fine so long as the TH1F called histid has equal bins.
If histid has been set up with variable binning however, the
bin assignment of the data seems to be corrupt.
Perhaps there is something special I need to do for this
case. Can anyone comment?
