Steps to repro:

1. Open attached project;
2. In the Project folder multiselect four Rock texture files by using Shift-click;
3. Right mouse and click 'Reimport'.

Expected result:
Texture is reimported without errors.

Actual result:

Errors:
'Could not create texture from Assets/Rock_AO.png: File could not be read'

are thrown. See attached screenshot.

Notes:
- Reproducible in 2017.1.0b4, 5.6.0p4, 5.5.2p1;
- Reproducible on OSX 10.12.3 and Windows 10;
- Reproducible only for these specific texture files, not reproducible for other textures;
- There is no valid workaround for this issue. Tried lots of things, like reimporting, deleting/restoring, etc.
