Translation breaks in the middle of a moderately long string for no apparent reason

v0.9.7.1 installed by brew on MacOS, default configuration

trans en:de -brief "today, tomorrow, yesterday, next week, next month, next year, monday, tuesday, wednesday, thursday, friday, saturday, sunday, one object, two euros, three clothes, four tomatoes, five boys, six girls, seven men, eight women, nine dogs, ten cats, eleven papers, twelve pens, thirteen smartphones, january, february"

This example breaks at six girls for no apparent reason. It happens on some languages (de) and not others (fr). No error message.

I cannot reproduce the issue when submitting directly on google translate web app.

Changing the engine to bing (-e bing) seems to fix this.
