Description
This coordinate system is total crap. The data projected in this CRS cannot be re-projected to other systems. “Pulkovo 1942(58) (GDAL compatible)” as the project's CRT creates a mess. Some screen shots will be added to illustrate my opinion. Four different grids are mapped. Note the travel of the red lines representing the “Pulkovo 1942(58) (GDAL compatible)” grid.
Tested with 1.7.1. The same problem with 1.9.90-Alpha QGIS code revision f61988e
The CRS “EPSG:44179 Pulkovo 1942(58) (GDAL compatible)” should be removed from the list.

QGIS syncs it's CRS with GDAL. So this should probably be taken there. But you also might want to check if the CRS is in the latest version of GDAL too.

If it's so why this CRS is listed nowhere else except in QGIS? E.g. GRASS on the same system (= using the same GDAL?) does not provide such CRS.
This CRS is mentioned only in QGIS resources:
/usr/share/qgis/resources/srs.db
C:\\OSGeo4W\\apps\\qgis\
esources\\srs.db
C:\\OSGeo4W\\apps\\qgis-dev\

Right. The CRS are only updated, but not removed.

Well, in Qgis <1.7 it wasn't any "total crap" ;p It was painful but essential workaround to allow Qgis to recognize proj strings without +towgs parameter (coming from older GDAL versions, ArcGIS etc).
In Qgis 1.7 it became unnecessary and, in the same time, incompatible, so please backport it to 1.7
But first please restore 900913 for one important reason: If a WMS supports EPSG:900913 and not EPSG:3785, then it's unavailable for Qgis now. Also OpenLayersPlugin use it (what is smaller problem, as it can be updated to 3785). Finally, I believe 900913 is better recognizable than 3785.

Hi Jurgen,
in QGIS master I don't see anymore CRSs like the Google Mercator, maybe a side effect of this fix?
