probleme when loading one leadtime only with the new Load

Hi,

When I try these script with new Load

  meantemp=Load("tas", c("b0cm","b0gq"), obs = "ERAint",
    sdates=c("19900501"), nleadtime = 4, nmember = 10, leadtimemin = 1,
    leadtimemax = 1, storefreq = "monthly", sampleperiod = 1,
    method = "conservative", output="areave")

I get the following error message

Error in checkForRemoteErrors(val) : 
  2 nodes produced errors; first error: missing value where TRUE/FALSE needed

While this one (which select 2 lead times instead of one) works fine:

  meantemp=Load("tas", c("b0cm","b0gq"), obs = "ERAint",
    sdates=c("19900501"), nleadtime = 4, nmember = 10, leadtimemin = 1,
    leadtimemax = 2, storefreq = "monthly", sampleperiod = 1,
    method = "conservative", output="areave")

I have also tried different experiments, different start dates, different variable, different lead time values and different type of output (lonlat and areave) and the results remains the same: it does not work with one leadtime and it works with two or more.
