Pairwise distribution in gbm crash under gbm.fit interface

[GoogleCodeExporter]

Pairwise regression is fine with formula interface, but when
I try it with gbm.fit, the same model the Rgui crash.

This is my naive
model:

gbm1<-gbm.fit(x=train[,c(2,4)],
y=train[,1],
n.trees=1000,

distribution = list(name="pairwise",group="query",metric="conc"),

interaction.depth = 2,
n.minobsinnode = 30,
shrinkage = 0.01,
bag.
fraction = 0.95,
verbose=TRUE)

Is it a known issue / restriction or
is a bug?

Thank you for your work!
