just upgraded to 1.3.1 and noticed, that in some albums above certain images there was a php warning: "division by zero error in ... forgot line --- the php file was Image(s?).php"
i found nothing about this behaviour in this forum, so i think, some will find this usefull:
delete the specific image (the error message appears above it) and re-upload it to the server. this will make the message dissapear.

This is because of of the function getDimensions in Image.php.
I've run into this error before myself and just put in a check
to make sure it doesn't try to divide by zero.
