Scilab error to get help

[cblasius]

Hello!

I obtain the following error wen I type in Scilab 4-1:

-->help printf
 !--error 999 
TCL_EvalFile, at line 3 of 
file /usr/local/lib/scilab/tcl/sciGUI/sciEditVar.tcl
at line       9 of function sciGUI_init called by :  
line    14 of function sciGUIhelp called by :  
line    23 of function run_help called by :  
line    20 of function browsehelp called by :  
line    25 of function help called by :  
help printf

How to repair this? Thanks in advance.
I work on 6.2-PRERELEASE.
