That's a bug all right. stack was initially intended for 1D series,  
not 2D ones. I'll check what I can do.

Meanwhile, you could:
* make sure that your series are compatible: same frequency, same  
starting and endings dates, same intervals between the dates
* stack the series using ma.column_stack : that gives you a masked array
* view the output as a TimeSeries, and set its dates to the dates of  
the input.
