R help - Oct 2006 - Haplo.Stats: error (recursive default argument reference)

Dear colleagues,

I face a problem doing haplotype analyses with haplostats: when I use 
the haplo.em function, the programme gives an error message because of 
'recursive default argument reference.' I am not able to figure out what
this means. Could you perhaps help me?

The full output is the following:
 > library(haplo.stats)
 > datafile.dat<-read.table("datafile.dat",header=TRUE)
 > attach(datafile.dat)
 > names(datafile.dat)
 [1] "SEXE" "AGE" "OUTCOME1"  "OUTCOME2"
"OUTCOME3" "OUTCOME4"
 [7] "OUTCOME5" "SNP1X" "SNP1Y" "SNP2X"
"SNP2Y" "SNP3X"
[13] "SNP3Y" "SNP4X" "SNP4Y" "SNP5X"
"SNP5Y" "SNP6X"
[19] "SNP6Y" "SNP7X" "SNP7Y"
 > block1<-datafile.dat[,c(8:21)]
 >
loci<-c("1","2","3","4","5","6","7")
 > em<-haplo.em(geno=block1,locus.label=loci,miss.val=c(0,NA))
Error in .Call("R_lazyLoadDBfetch", key, file, compressed, hook,
PACKAGE
= "base") :
        recursive default argument reference

Thank you very much in advance!
