Qgis not using '+towgs' proj parameters when OTF reprojection

Latest 'release-1_7' build and current master is
not using '+towgs' proj parameters when using on-the-fly reprojection.
It is visible when overlaying two layers in different projection where
'towgs' parameter is needed to reproject data accurately. Currently the
error is the same as it would be without specifying 'towgs' parameter.
I have found that Qgis is not using 'towgs' only if using one of the
projections from installed projection database. If I create custom
projection by 'Settings -> Custom CRS' it is working correctly.
