           Version: 3.5.4 release

Created attachment 65418
  --> https://bugs.freedesktop.org/attachment.cgi?id=65418
Example MSO 2007 document containing formulae

How to reproduce:
- Import DOCX document from attachment
- Both formulae are editable
- Save document as ODT
- Reload ODT in LO

Expected result:
- Both formulae are editable

Actual result:
- Only first formula is editable as formula
- The frame edit dialog appears when trying to edit the second formula

Settings under Options - Load/Save - Microsoft Office:

MathType to LibreOffice Math or reverse: "Load and convert the object" and
"Convert and save the object" are both checked.

The problem is actually worse with the original unstripped DOCX document.
There all formulae are replaced in the re-opened ODT with a square showing a
"Object ##" text.

Problem observed in: 
Libreoffice 3.5.4 on openSuSE 11.4 (64-bit)
Libreoffice-master version 3.7.0.0.alpha0+ (Build ID: 769e2b5) on openSuSE
11.4 (32-bit)
Libreoffice version 3.6.0.4 (Build ID: 360m1(Build:104)) on openSuSE 11.4
(32-bit)

My full debug master build produces these lines during the export to ODT

warn:legacy.osl:9892:1:/home/stephan/Software/libreoffice-master/core/starmath/source/mathmlexport.cxx:1485:
Warning: failed to export a node?
warn:legacy.osl:9892:1:/home/stephan/Software/libreoffice-master/core/unotools/source/config/configmgr.cxx:208:
OSL_ASSERT: items_.empty()

And on the reloading of the ODT

warn:legacy.osl:10126:1:/home/stephan/Software/libreoffice-master/core/comphelper/source/container/embeddedobjectcontainer.cxx:419:
A freshly create object should be running always!
