bug#32597: gdb gud-watch speedbar no visible actions

[Ergus]

1) "M-x speedbar" requires to be called twice for the first speedbar open. If
this is not a bug, it is very weird.

2) Debugging with gdb in emacs a C program I added a gud-watch for a struct
variable. Going to the speedbar I try to open the struct tree [+] with <SPC> but
it does nothing (i don't try mouse click because I am in a terminal session).

- It requires to quit (q) and open the "M-x speedbar" again to show the
speedbar updated with the tree opened. It opens depends if I pressed
<SPC> odd or even times before q.

- The opposite (close the tree) works properly without exit needed, but I can't
open it again (previous explained behavior).

- I tried this with -Q option to check that it was not a mistake in my
configuration.

- The speedbar in: "emacs -Q -f speedbar" works fine without this issue.

- With emacs in gui there is not problem either.
