comment GRASS-QGIS Linking error
Your GRASS libs are linked to GDAL 1.8. It is obvious. Of course, you could link the libs back to GDAL 1.9.2 but I would not advise to do that. Again, recompile your GRASS with GDAL 1.9.2. It should solve the problem.

comment How to fix crashes after update to Ubuntu 12.04?
Why your advise is so difficult? In Linux everything is simple: one shouldn't reinstall program every time it crashes (or a fortriori run virtual machine), but instead to trace the bug and report!

You act like a Windows user. Try to run the program in terminal and see the output.

Try this 'SELECT ref,ST_Distance(r.geom,ST_SetSRID(ST_MakePoint(75.252398, 19.905008),4326)) FROM roads r ORDER BY 2 ASC LIMIT 1;'

Minimal working example, e.g. provide SQL code that you are trying to execute. ST_ClosestPoint returns geometry, consult postgis.org/docs/ST_ClosestPoint.html

There is no such function as ST_ClosedPoint in PostGIS. Please provide MWE that reproduces the problem.
