Localisation issue

I find out a potential bug.
When setting emonCMS profile from en_EN to fr_FR, i tried to add some input processing for my new temp sensors.

Node_28_1 => x 0.001 => Log to a new feed: node_28_volt

It started to acting weird. In the inputs list, i saw " X and log" but editing this input => blank processing list.
Was acting the same with all newly added temp nodes..... and created feed was never filed.

So i installed phpmyadmin and looking the emoncms base, inputs table, i discovered in this input (28) process list:
2:0,001,1:50
Older sensors input process list were this kind: 2:0.001,1:50

So switching language in my profile made the decimal character change from . to ,
It's a normal language behavior but in my opinion, it shouldn't change the decimal character when writing to Mysql.
