[fxruby-users] table.extractText problem

Hello,
On a linux system with:
ruby 1.8.6 (2007-06-07 patchlevel 36) [i486-linux]
FXRuby-1.6.12
libfox 1.6.25-1

I tried to use the FXTable::extractText like this

     maxrow = MAX_ROW - 1
      maxcol = MAX_COL - 1
      printout = @table.extractText(0 , maxrow , 0 , maxcol , cs="\t", rs="\n")
      #  Write the file
      File.open(saveDialog.filename, "w").write(printout)

then I got this output:
__________________________________
discretizer.rb:3408: [BUG] Segmentation fault
ruby 1.8.6 (2007-06-07) [i486-linux]
_________________________________

if I change
     maxrow = MAX_ROW - 100
      maxcol = MAX_COL - 100

Then I get:
