The 
sign is written in A before the b
minim, which may have mislead the engraver of GE1; however, nothing indicates that Chopin's intention would be pressing the pedal from the beginning of the bar. From the practical point of view, pressing the pedal in the middle of the bar is the only solution enabling to clearly hold the c-b-c1-e1 chord during the entire 2nd half of the bar. The absence of pedalling in FE (→EE1) is most probably a result of an oversight.
