Issue
Nemo crashes when dragging files or folders when window is below a certain size.

Steps to reproduce

1. $ nemo ~
2. Adjust icon zoom level to the maximum setting (not necessary, but it makes the bug easier to reproduce)
3. Reduce the nemo's window width. Stop right before the right border of the file/folders is covered by the window border
4. Select any file or directory and drag in any direction.

Expected behaviour
Nemo crashes with the following error:
file ../../libnemo-private/nemo-icon-info.c: line 696 (nemo_get_desktop_icon_size_for_zoom_level): should not be reached
Segmentation fault (core dumped)

Other information

The size threshold below which nemo will crash depends on the size of the icons. The window has to be narrower if icons are small in order to reproduce the issue.
