No, I don't. As a practical matter, such scenarios occur approximately 
never. This can be used as an interview question if the candidate lists 
localization experience - it's a good trap.

Consider for example a dialog box with 12 localizable texts. It makes no 
sense to abort its creation if the formatting or localization of the second 
text fails, and neither does it make sense to leave the rest of the texts 
blank or untranslated/unformatted. In practice, if these functions throw, 
you'll have to wrap each and every call with a try block, which is an 
obvious indication that these functions shouldn't throw.
