I've written some example C code to trigger the bug.  It's getting the terminal
size using the TIOCGWINSZ ioctl to get the terminal size.  The TIOCGWINSZ ioctl
call reports the correct size only when not using Konsole's -e option.  With
the -e option, the size is always reported as 0x0:

#include <stdio.h>
#include <sys/ioctl.h>
#include <termios.h>

int main( void )
{
    struct winsize size;
    size.ws_col = size.ws_row = 0;
    if (ioctl(0, TIOCGWINSZ, &size) < 0) {
        printf("Error: ioctl failed.\n");
        return 1;
    }
    printf("Terminal size: %dx%d\n", size.ws_col, size.ws_row);
    printf("[ENTER to quit.]");
    scanf("%*[^\n]");
    return 0;
}
