Seqlab extension problem : EXE line too long ?

Hi,

Has anyone experienced the following problem with the seqlab 
extensions (GCG 9.1) :

When the EXE line (which describe the actual command with defined variables
for each parameter) is too long ( > 338 characters ?? ), the Seqlab interface 
crashes, with the following error message :

SeqLab Server: client unexpectedly went away.
Bad system call



Here is my extension definition (a test program doing nothing real) :
I have tested the limit with the name one 1 qualifier s12345bis3 !! (sorry)
All the parameters are defined as strings.

----------------------------------------------------------------------
EXTERNAL
EXE  $essaiseqlab $s12345bis3 $s1 $sbis4 $s2 $sbis5 $s3 $sbis6 $s4 $sbis7 $s5 $s
bis8 $s6 $sbis9 $s7 $s8 $s9 $sbis20 $sbis21 $sbis22 $s20 $sbis23 $s21 $sbis24 $s
22 $s23 $sbis1 $s24 $s19 $sbis2 $ster1 $ster2 $ster3 $ster4 $sbis10 $sbis11 $sbi
s12 $s10 $sbis13 $s11 $sbis14 $s12 $sbis15 $s13 $sbis16 $s14 $sbis17 $s15 $sbis1
8 $s16 $sbis19 $s17 $s18

Main {
   Label 
       prompt = TEST VERSION -- test for Seqlab
   End
   Blank

   Text
     id = essaiseqlab
     qualifier = essaiseqlab
     method = "echo"
     display = False
     default = "echo"
     answer = False
   End

   Text
     id = s1
     qualifier = s1
     method = value
     prompt = string
     default = 
     answer = False
   End

[each parameter s... is defined the same way]
}
Optional {

}
----------------------------------------------------------------------

Thanks in advance,
