Bug Description

Hello

with a large collection 100k+ i see only the last thumbnails. With recreate thumbnails i can see at one point the first thumbnail was remove when a new thumbnail at the end was create.
Version is xubuntu 16.04.01 and picty testing-r800.

regards Thomas

Can you open from a terminal and see if there are any obvious error
messages? What sort of images (jpeg? Raw?) and how old? Exiv2 may have
issues with some older formats. Also are you using the default
thumbnailing settings? (Under collection settings.)
