'open image..' dialog, if selecting multiple images

[ncmprhnsbl]

arch linux, git head
Seems to be an issue with the 'open image..' dialog, if selecting multiple images (ctrl+click) ...first image opens okay, but navigating to the second(and more) there's just : Fail to open file:<looks like recent clipboard history and/or random junk>:no such file or directory .
Then navigating back to the first image also fails.
Opening single image(ie the entire folder) is ok.
Open multiple images from a filemanager is ok.
