             Bug #: 55156
           Summary: Hang on accessing any pane in the application Options
                    dialog, when Cinch is running (related to Mac OS
                    accessibility)
    Classification: Unclassified
           Product: LibreOffice
           Version: 3.3.0 release
          Platform: x86-64 (AMD64)
        OS/Version: Mac OS X (All)
            Status: UNCONFIRMED
          Severity: major
          Priority: medium
         Component: Libreoffice
        AssignedTo: [email protected]
        ReportedBy: [email protected]


When Cinch, a popular window management utility for Mac OS X, is installed and
running, any attempt to access any pane of the application Options dialog leads
to a hang. (See “steps to reproduce” below for details!)

This is very probably yet another bug in the LibreOffice code related to Mac OS
X accessibility features, because
 * Cinch relies heavily on these accessibility features (it requires the system
   preference “Universal Access > Enable access for assistive devices”
   to be checked), and
 * the log file created by Mac OS X when I forced quit LibreOffice because of
   the hang contains many references to accessibility stuff.

NB: I create a new bug report for this issue, because no one of the existing
bug reports about problems accessing panes of the application Options dialog
covers this special issue clearly.


Steps to reproduce:
-------------------
1) Download Cinch, available from
       http://www.irradiatedsoftware.com/cinch/index.html
   (ShareWare, but you can try it for free, just as I did).
2) Start it just like a normal application.
   -> During startup, Cinch will automatically enable
   the system preference “Enable access for assistive devices”
   (in “System Preferences > Universal Access”) for you.
3) Optional: Rename your LibreOffice user profile folder,
   to preclude any influence of local settings on the test results.
4) Start LibreOffice.
   -> The Start Center window appears.
5) Select “LibreOffice > Preferences...” from the menu bar.
   -> the dialog window “Options” appears,
   it shows by default the first pane: “LibreOffice > User data”.
6) Now try to select any other pane from the list at the left,
   e.g. “General”.
   -> First, nothing happens;
   then the spinning cursor appears,
   LibreOffice hangs.
   [In the case that you *can* select another pane (I have seen this once),
   just try to repeat this, i.e. select yet another pane;
   now LibreOffice hangs.]

Attached to this bug report you will find the log file created by Mac OS X when
I forced quit LibreOffice because of this hang.


Reproducible with:
..................
* LibreOffice 3.3.0 (OOO330m19, Build:6, tag libreoffice-3.3.0.4)
* LibreOffice 3.5.6.2 (Build ID: e0fbe70-dcba98b-297ab39-994e618-0f858f0)
* LibreOffice 3.6.2.1 (Build ID: ba822cc)
* LOdev 3.7.0.0.alpha0+, Build ID: 01e6335, Pull time: 2012-09-18 04:23:03
* and probably every other LibreOffice version.

This bug is NOT identical to bug 47368, and NOT fixed by the two (three)
patches for it.
