Roland65, thank you for reporting this and helping make Ubuntu better.

To advise, this isn't confirmed a bug in either libatk-adaptor, or
LibreOffice, given you are using a 3rd party extension. Also, that
extension wasn't advised compatible with your version of LIbreOffice as
per http://extensions.libreoffice.org/extension-center/texmaths-1 .

Despite this:
1) Do you have any other 3rd party software installed (extensions, PPAs, etc.)?
2) Is this an issue that started to happen after a software update?
3) Does this issue occur with the latest supported version of LibreOffice via 
https://launchpad.net/~libreoffice ?

   Importance: Undecided => Low

** Changed in: libreoffice (Ubuntu)
       Status: New => Incomplete

** Summary changed:

- libatk-adaptor breaks down the LibreOffice TexMaths extension
+ TexMaths extension issue after installing libatk-adaptor

** Description changed:

- If the package libatk-adaptor is installed on Ubuntu (as a dependency of
- gnome-orca for example), it breaks down the LibreOffice TexMaths
- extension. TexMaths is a popular extension used to enter / edit LaTeX
- equations on LibreOffice (see http://roland65.free.fr/texmaths).
+ The TexMaths extension has an issue if the package libatk-adaptor is
+ installed on Ubuntu (as a dependency of gnome-orca for example).
+ TexMaths is a popular extension used to enter / edit LaTeX equations on
+ LibreOffice (see http://roland65.free.fr/texmaths).
  
  Step to reproduce the bug:
  
  1. It is assumed that LibreOffice 5.1.4 (with at least the Writer and
  Draw components) is installed on Ubuntu. It is also assumed that libatk-
  adaptor is installed.
  
  2. Install texlive:
  sudo apt-get install texlive
  
  3. Download and install the TexMaths extension (version 0.42) from
  there: https://sourceforge.net/projects/texmaths/files/0.42/
  
  4. Create a new empty Writer document, then click on the Pi icon (this
  is the TexMaths icon) and in the window that opens, type: 'x(t)+y(t)'
  (without the quotes), then click on the LaTeX button. This generates an
  SVG image of the 'x(t)+y(t)' equation.
  
  5. Select the SVG image of the equation by left clicking on it. Then
  click on the Pi icon. Now, instead of editing the equation, an error
  message is displayed: "The selected object is not a TexMaths equation...
  Please unselect it and call the macro again...".
  
  6. Now, right click on the SVG image and select the 'Description' menu
  voice. In the window that opens, the description is empty and does not
  contain the equation text, as it should.
  
  7. Now purge (and not just remove) the libatk-adaptor package:
  
  sudo apt-get purge libatk-adaptor
  
  then logout and login and repeat the steps 4, 5, and 6: everything is OK
  and the equation can be edited as usual.
  
  Another way to remove the bug instead of purging libatk-adaptor is to
  rename the file: /etc/X11/Xsession.d/90atk-adaptor to
  /etc/X11/Xsession.d/90atk-adaptor.orig . Then logout and login.
  
  I don't know if the bug is from the LibreOffice side or from the libatk-
  adaptor side, so I reported this bug to both packages.
