Hi, I am the writer of the french patch.
The issue comes from the fact that something has been added to PvMP+ but not translated in french so the variable doesn't exists and the plugin crashes. This is very stupid because we could use english translation as a backend of other language but that isn't the case here.
Another issue is a problem of translation of "The" in french. While there is only one word in english, there are 3 words in french ("Le", "La", "Les") - that's why I put 3 value numbered 1 2 3 to parse fight log.
This patch does not add any functionnality. Therefore, it shouldn't be used for english game and I think it would break the parsing of deutsch and russian games.
Indeed, I forgot to take into account the new commands for kinshinp channel and fellowship channel in french client. I may correct it during hollydays (that's only a line but I need to find the sources of the patch on my computer, correct it, test it and upload it).
However, if you see other problems of french translation (or other language) or want some improvements for PvMP+, tell it here. I may put them in the patch
EDIT : I won't correct error of parsing with plugindata, you can use Vindar's patch for that (I don't remember wether PvMP+ needs it or not)
