Description Terrence Enger 2017-09-04 14:15:31 UTC 
Created attachment 136011 [details]
output from bibisect in daily Linux dbgutil repository

STR

(1) export SAL_USE_VCLPLUGIN=gtk3

(2) run soffice with parameters
        --norestore --nologo --impress
    Program presents dialog "Select a Template".
    
(3) Select first offered template, "Alizarin", and click <Open>.
    Program returns focus to the impress window "Untitled 1" and
    changes first slide according to the template.

(4) Type "<ctrl>+Q".  Program terminates with the assertion.  From the
    terminal output (lines rewrapped):

        warn:svx:9087:1:svtools/source/control/valueacc.cxx:664:
            Calling disposed object. Throwing exception:

                void SfxListener::StartListening(SfxBroadcaster&, bool):
                    Assertion `!(bListeningAlready && !bPreventDuplicates)
                               && "duplicate listener,
                                   try building with DBG_UTIL to find the
                                   other insert site."
                              ' failed.
        Application Error
        Fatal exception: Signal 6

The problem also happens with a new user directory.

I see this working on debian-stretch with xfce desktop and daily Linux
dbgutil bibisect repository.
Comment 1 Terrence Enger 2017-09-04 14:24:43 UTC 
I now see that my bibisection merely found the day when the assertion
was committed to master.  Nothing useful here.  I am marking the
attached bibisect output obsolete.
Comment 2 Julien Nabet 2017-09-06 18:46:34 UTC 
On pc Debian x86-64 with master sources updated today + enable-dbgutil + gtk3, I don't reproduce this.
What's the last commit of your build? Indeed, Noel and Michael had fixed some assertions cases related to the duplicate listener.
Comment 3 Terrence Enger 2017-09-07 13:19:16 UTC 
Now, I can no longer reproduce the problem, neither with recent
versions from the daily Linux dbgutil bibisect repository, nor with
the versions where I first saw the problem and bibisected.  What I
wonder can I be doing differently today?

If anybody else can reproduce the problem, that would be good.  So
would be any advice about what I can do to clarify the situation.  In
the absence of either of these, I am leaning toward resolving this bug
INVALID.
Comment 4 Michael Stahl (allotropia) 2017-09-08 19:01:28 UTC 
fixed by commit 53587dc7969b023416d865b516b7e800fc5de33a
"sd: AccessibleSlideSorterView: don't register twice at ViewShell"
Comment 5 Terrence Enger 2017-09-13 15:35:24 UTC 
Thank you, Michael.

Considering that the problem disappeared for me, it is not worth much,
but ...

I see no assertion in daily Linux dbgutil bibisect repository version
2017-09-11.  I am setting status VERIFIED FIXED.
