Dynamic Texture (String) Error when fed with Spread

Hey everyone.

Working with web pictures i stumbled upon this error:
When feeding dynamic texture (string) with a spread the TTY renderer spits out this message:
00:00:03 * : Texture (Width: 256, Height: 256, Format: X8R8G8B8, Mip Map Count: 1, Filter: None, Mirror X, Mirror Y, Mirror Z, Dither, Srgb In, Srgb Out, MipFilter: None, Mirror X, Mirror Y, Mirror Z, Dither, Srgb In, Srgb Out) couldn’t be created because of unknown reasons.

The textures are shown properly but I am somehow suspicious that this might cause program crashes when handling lots of pictures. Any ideas how to get rid of this error?
Check it out yourself with the attached patch.
