R gnome produces errors?: a clue!

I've got something that might be a clue to understand
the strange behaviour of lda in R --gui="gnome":

in R --vanilla:

library(MASS)
load("mod23puriflda.rda")

a <- lda.default(x=mod23puriflda[,2:5],grouping=mod23puriflda[,6],CV=F)

works fine. I save lda.default as a local rda file:

milda.nognome <- lda.default
save(milda.nognome,file="milda.nognome.rda")

Then in R --vanilla --gui="gnome"

library(MASS)
load("mod23puriflda.rda")

a

<-lda.default(x=mod23puriflda[,2:5],grouping=mod23puriflda[,6],CV=F,method="mo
ment")
Error in lda.default(x = mod23puriflda[, 2:5], grouping = mod23puriflda[,
: 
      length of dimnames[2] not equal to array extent
In addition: Warning message: 
variables are collinear in: lda.default(x = mod23puriflda[, 2:5], grouping
= mod23puriflda[,  

Does not work, BUT:

load("milda.nognome.rda")
a <-

milda.nognome(x=mod23puriflda[,2:5],grouping=mod23puriflda[,6],CV=F,method="mo
ment")

WORKS!!

and, still in  R --vanilla --gui="gnome", I save lda.default to another
rda file:

milda.gnome <- lda.default
save(milda.gnome,file="milda.gnome.rda")

Then back to R --vanilla

load("milda.gnome.rda")
a <- milda.gnome(x=mod23puriflda[,2:5],grouping=mod23puriflda[,6],CV=F)

Error in milda.gnome(x = mod23puriflda[, 2:5], grouping = mod23puriflda[,
:
        length of dimnames[2] not equal to array extent
In addition: Warning message:
variables are collinear in: milda.gnome(x = mod23puriflda[, 2:5], grouping
= mod23puriflda[,

Does not work !!

Therefore, gnome is really changing something, but what?
