When i run xterm with same parameters is everything OK., but in kdbg its opening xterm in fifo.

Perhaps kdbg is setting LINES/COLUMNS

I see that it is setting xterm's -geometry option.
Do the values for that correspond to the LINES/COLUMNS values?

Does konsole set LINES/COLUMNS?

Setting LINES/COLUMNS explicitly to override curses's notion of screensize
is long-established.

Setting those by the terminal emulator itself is long-depcrecated.
In xterm it only happens if the configure script is unable to find
a workable (compile-time) definition for TIOCSWINSZ.
