Description Yuriy Kozlov 2006-09-14 03:59:10 UTC

Version:           1.5.91 (using KDE KDE 3.5.4)
Installed from:    Ubuntu Packages
OS:                Linux

I had two documents in KWord, on two different machines both running Kubuntu Edgy with KOffice 1.6 Beta 1.

Each document had several in-line formulas and were saved in ODT (ODF) format.  When I open them with KWord, most (not all) of the contents of the formulas are gone.  The frames are still there.  OpenOffice.org 2.0 crashes when trying to open either of the documents.

In a couple formulas that remain intact, there are commas inserted between parentheses and the content between those parentheses.

I made a test file with just one formula.  I saved it in both KWord and ODF formats.  Either of those opened in KWord yields a blank frame.  When the ODT is opened in OpenOffice.org 2.0, the formula is there.

the test file

This contains one formula, created in KWord, that appears in OpenOffice but not
in KWord.

OpenDocument: Fix saving <semantics>, it does not infer mrows, so mrow is
manually added.
