Error in 'msgstr' during traduction

[nin2jardin]

In Launchpad, some translations containing '{0}' (without quotes) return the following error when submitting :
a format specification for argument {0} doesn't exist in 'msgstr'

For example, when sending

Erreur à l'initialisation du test {0} :

{1}

for the translation of :

Error initializing test {0}:

{1}

You need to use a proper ’. You probably use the '.

Thank you but there is no apostrophe in this dialog.
There is only a line break and a space.
The ref# of the key I try to translate is 1069.
I will try to add here all the keys impacted if yu need them.

What about "l’initialisation"? How would you call that? ;-)

BTW: Even if there is no error when you enter a ', then it may be that Java does not display that sign. But I'm not Java Guru enough to know the exact reason for this.

OK, I apologize. I didn't noticed that one :)

I tried by copy/paste your apostrophe and it worked, thanks.
I don't have this one directly on my french keyboard but it's a workaround.
I've translated all the messages affected.

I don't know really what to do with the status of this ticket now...
It canreappear with future messages, but can be easily "workarounded" (excuse my english).
