Can you use any GRASS layers from GDAL?   The GRASS plugin for GDAL might need
a rebuild.  Perhaps the old plugins don't work with the new GRASS.

As far a QGIS is concerned I don't see a direct dependency to gdal 1.5
anywhere in the packages.

The problem here is that QGIS GRASS plugin justs expects GDAL to have GRASS
plugins, but doesn't directly link with them (which would produce a specific
dependency automatically).

The dependency to libgdal1-*-grass is just there to make sure GDAL has GRASS
plugins, but that assumes that there is only one set of plugins available.  If
the latter is not the case apt might choose to install libgdal1-1.5.0-grass
(and it's dependencies) over libgdal1-1.6.0-grass.

I don't known how to express a dependency that would deal with this
automatically (and would work with all repositories).  Perhaps simply changing
the order is enough.

A workaround is to install libgdal1-1.6.0-grass beforehand - obviously that
doesn't help with the crash if the GRASS plugins for GDAL don't currently work
at all.
