[Issues] Weird BiasFrame select

[Jan Snigula]

Hi all,

select on BiasFrames works in a strange way, doing

query=BiasFrame.select(instrument='WFI',chip='ccd50')

returns a <astro.main.BiasFrame.BiasFrame object at 0x2aa3f0aa10>

and not a DBSelect object as expected.

This happens in the latest CVS version.

Cheers,

Jan
