[DGD] Error in kernel auto object

[ind at o2.pl]

Hello

I receive the following error when I invoke 'editor' kfun with kernel:

Value is not an array
  46 receive_message   /kernel/obj/telnet (#64)
 199 receive_message   /kernel/lib/connection (/kernel/obj/telnet#64)
 786 receive_message   /u/System/obj/immo (#67)
 493 command          /u/System/obj/immo (#67)
 389 immo_command  /u/System/obj/immo (#67)
  36 command_ed        /u/System/obj/immo (#67)
  34 start             /u/System/obj/ed (#69)
1550 editor            /kernel/lib/auto (/u/System/obj/ed#69)

this is where

mixed *info;
...
info = ::call_trace()[1][TRACE_FIRSTARG][1];

and that value is just "System", not an array.

Is it my fault? I had working version of this command and everything was 
ok, but now after refactoring this is how it looks :)
This error is not affecting the editor, it works, but throws error msg 
every time on start.
