1. 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.

Currently the odt exporter doesn't peek in to the latex fragment and
infer what manner of equation it is. This is something that I could take
up ...

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. Can you confirm that the expectations above are *not*
your own but that of *any* user?
