[GRASS-user] mysterious error (WARNING: Cannot open old vector on level 2)

[Henry House]

I'm having mysterious errors trying to use various modules in my
database (GRASS 6.1 running on Debian), which contains mapsets
PERMANENT and hajhouse.

example:
   GRASS 6.1.cvs (sacramento_sanjoaquin):~/grass > ps.map in=Scripts/psmap_script output=out.ps 
   
   WARNING: Cannot open old vector soil at hajhouse on level 2
   ERROR: soil in hajhouse : can't open vector file

g.list vect reports:
   vector files available in mapset hajhouse:
   soil 
   
   vector files available in mapset PERMANENT:
   cont_10      cty_bounds   hydro        plsa         rd_local
   rd_state     
   rd_usa       soilmu_a_sac soilmu_l_sac soilmu_p_sac soilsa_a_sac
   soilsf_l_sac 
   soilsf_p_sac urban        

Trying to use v.out.ogr fails with the same error. Trying to display a
layer in QGIS (via grass plugin) fails with a rather unhelpful error
that the layer is not a valid layer. The error presented is the same
for soilmu_a_sac at PERMANENT and soil at hajhouse but some other layers in
this database work fine with all GRASS modules. All the layers
including the problematic ones display fine in the GRASS GIS manager,
however.

What is puzzling and frustrating about this is that it worked fine a
month or so ago.  Then I set work in GRASS aside for a month and now
that I have resumed the errors are here.  I have not altered my GRASS
binaries or support files in the meanwhile, and AFAIK my OS library
versions have not been updated either.
