   This output is from emacs-x with both patches
applied:

    % src/emacs
    X protocol error: BadDrawable (invalid Pixmap or Window parameter) on 
protocol request 134
    Serial no: 1318
    Failing resource ID (if any): 0x5901a002
    Minor code: 14
    This is a bug!  Please report this to bug-gnu-emacs@gnu.org!

Note that I had to move the comma at the end of

    > +         "Minor code: %d\n",

to the end of the following line. I only mention it in case
it's a sign that something else was intended.

Standing by for the next iteration. Thank you!
