FileRunner & X selection & GTK2

[Bob Marcan <bob interstudio homeunix net>]

This is the code fragment from FileRunner:
...
proc GetFileListBoxSTRING_Selection {offset maxBytes } {
  global glob
  set l {}
  foreach inst {left right} {
    foreach sel [$glob(win,$inst).frame_listb.listbox1 curselection] {
#+ this is wrapped
      set l "$l $glob($inst,pwd)/[lindex [lindex $glob($inst,filelist)
$sel] 1]"
#- this is wrapped
    }
  }
  return [string range $l 1 $maxBytes]
}
...

When you select entry(ies) and then paste into
xterm,xemacs.., gcombust(GTK1), output is O.K.:
[encijan ~]$ /home/bob/bin/FileRunner/fr /home/bob/bin/FileRunner/fr.gif

gnome-terminal,mozilla,gedit:
 fr                         111583 040801 14:37:03 rwxr-xr-x bob/wheel
 fr.gif                       1237 991230 18:21:49 rw-r--r-- bob/wheel

It doesn't matter for the gnome-terminal or gedit, but when i want to 
paste something into mozilla mail, you can hear &*%#%$%$$^%$ from my mouth.

This is on Linux FC2, latest patches.
LC_ALL=C

What's going on?
Probably it is GTK2 problem.
Does anybody have an explanation or solution?
It's so handy feature, but now ...

Best regards & TIA, Bob
