Shotwell crashes exporting photos to directory

[marcocassisa]

Shotwell crashes when I select a "tag" and then export some (edit: a quite large number of) photos to a directory. Only some photo is actually exported.

Btw, occasionally (during some try, can't reproduce) some filename is wrong (instead of DSC_012345.jpg something like DSC_012345.jpg023556)

# shotwell
