Interesting.

This should not happen.  Can you get us a backtrace by checking the
"Enter Debugger on Error" entry in the Options menu before trying the
"Send Bug Report...".  (My apologies if this has been reported before
and already fixed.)

I suppose the following

 > Major mode: Dired by name

is not part of the recipe?  Anyway, back to your first report.  Does

 >> One of the windows **splits vertically**(!!)

mean that the new window appears on the right of another window or below
it?  Also please tell us which window was split - the upper one or the
lower one.  If the new window appears below, then in the window that
gets split please do (before the split):

M-: (window-total-height) RET

and

C-h v split-height-threshold

If the new window appears on the right, please do

M-: (window-total-width) RET

and

C-h v split-width-threshold

instead.  In either case, tell us what gets printed by these.

Thanks, martin
