In my opinion, the problems when reading old files (bugs #374,#375,#376)
are unacceptable.
I suggest a different approach for this problem:
the conversion should be done by an outside script and not in LyX source code.
Attached is a proof of concept script that converts minipages & float from
old format to new format.
The script correctly handle the test case of bugs #374,#375,#376.
Comments?
