[Shotwell] Pictures date before 1900 - not possible ?

[Thierry Le Guillou]

Hello,
I have a problem with family pictures, taken in 1896. I scanned them and 
I changed the date to the date they were taken : june 1896.
But Shotwell cannot change date before 1900 (unlike other software). And 
even if I change the date with an other application, Shotwell is not 
able to manage them and put these pictures in an event in 1969 !
Could it be possible in next release to unlock this limitation ?
Thanks in advance and thanks for this great software.
Thierry
