Rainer,

Two extra pieces of information might be helpful, the traceback() of the 
error (to see which R code was used last) and the GRASS version. If you 
felt like running readRAST6() under debug(), it would be even clearer 
whether execution is following the plugin or r.out.gdal forks in the code.

I ask about the GRASS version because I seem to remember a file name 
length limitation in older versions.
