It's not the current version (I think deb packages aren't avaiable for
Debian stable and I haven't found the time for self compiling):

platform i386-pc-linux-gnu
arch     i386             
os       linux-gnu        
system   i386, linux-gnu  
status                    
major    1                
minor    3.1              
year     2001             
month    08               
day      31               
language R        

So it sound that's a problem of version 1.3.1, fixed in 1.4.0.

Thanks, Sven
