Upgrade woes - continued

[Peter]

Beginning the second day. I found these in the console:

(emacs:23113): Gtk-WARNING **: 00:11:51.947: no trigger event for menu popup

(emacs:22750): dconf-WARNING **: 23:31:25.201: failed to commit changes to
dconf: Error spawning command line “dbus-launch
--autolaunch=41eb1750243211de992d00e0 1836f13c --binary-syntax
--close-stderr”: Child process exited with code 1

So I started focussing on Dbus. Anyway, this is not a warning, this is
a Bug: unauthorized use of Dbus (emacs is compiled *WITHOUT* dbus).
( BTW, I found that the same goes for firefox: compiled WITHOUT dbus,
but nevertheless happily relies on it if it finds it working. Bug
report sent, probably they won't care about it either. We now finally
achieved to have in our Unix the security features as of Windows
3.0. )

The error message itself has the simple reason that dbus happened to
be compiled without X11 support (which I actually think is a good idea,
because if it cannot run, it cannot do much harm).

The other warning (no trigger event ...) is still unexplained.

But, the emacs stalls seemed to be independent of that, so it led
me to nothing.

So, after searching through all kinds of configurations and trying
lots of compile options, I focused on the fact that only one of my two
displays experienced the problem. Such an issue should normally be
solveable via comparative analysis.

I had a look into truss, and there the difference was obvious. I
start the application, then wait 60 seconds (to let things settle),
then click on a menu. And it goes like this:

For the well-behaving instance:

After few ms a writev() is sent to the X, and then things will proceed
and create the pulldown menu.

And here finally is the writev() sent and the menu unfolds -
31 seconds later. (Running with truss seems to slow things down.)

I don't know why it wants to read the auto-save-list, even less what
it might intend to do with that HELLO file...

Now with evening and morning, about this was the second day.
