You are using custom styles for your latex fragment 2. latex-to-mathml converter - as it stands today - assumes the latex fragment is completed in and of itself and doesn't honor the style settings. Putting 1 and 2 together, I am assuming that the XML created by the ODT emitter contains garbage which is causing LibreOffice to be confused. In my observation, ill-formed XML triggers "file is corrupt and should I repair the file?" from LibreOffice. A crash seems strange to me. 1. http://article.gmane.org/gmane.emacs.orgmode/48714 - Above link has my note on -ncf option to mathtoweb 2. http://orgmode.org/worg/org-faq.html - Above link has a note on how to debug corrupt odt files.

Currently the odt exporter doesn't peek in to the latex fragment and infer what manner of equation it is.

Being a non-latex user, I am not familiar with what the usual practice is. If the latter option is how captioned equations are normally typeset I can take it up.
