export ignores files with duplicate filenames
Mandatory: Shotwell version the issue was seen with
0.30.1 – “Celle”
The expected behaviour
If images with duplicate filenames are selected, I would expect "Export..." to offer to rename any files which have the same filename.
What was actually happening
"Export..." only puts one of the files in the target directory, and no error or dialog appears.
Steps to reproduce the issue
If I have two files DSC_0002.jpg and DSC_0002.jpg, I select them in Shotwell, and select "Export...", only one file is saved in the target directory.
