Please provide any additional information below.
I tried to change the translation file myself, replacing the left part of the assignment (which uses a nasty syntax with [=[ ]=] ) by the version I found in localization.lua (with only brackets and a \r), and I dont't get any crash. But I'm not sure my translation is really used.

there seems to be an issue with the upstream localizer app related to newlines, but that's the first time I'm seeing such an issue. actually, i would know a workaround, but for that i would need access to the english strings in the localizer.

This [=[ behavior happens inside the localizer when dealing with ascii characters.

Same thing happens with other addon also.
