OK, now I understand (thanks also to Kornel for the explanation). This is what happens: When converting from 500 to 501, the font settings of the not used flavour are filled in from the fontdefaults list in lyx_2_2.py. Thus, after a 503->500->503 roundtrip, you get the attached patch, which makes the tests fail. This is not a bug. The conversion 501->500 must be lossy, since the format 500 is not able to store the font information of the "not used" flavour. Therefore, the only exports which are guaranteed to work after a conversion to format 500 are the ones of the used flavour (\use_non_tex_fonts false or true). The other flavour may fail. IMHO it does not make sense to blindly test more and more combinations of conversions of the existing documents. I would rather put the energy in creating dedicated tests, e.g. for each lyx2lyx step. I must admit that I do not understand the current test strategy anymore, since there are several categories, and the test code became so complicated (e.g. running lyx2lyx in a loop or automagically changing document settings).
