If you have a space in an image file name, it's reported as an error. The makeSafe() function is called, but returns the file name with the spaces intact. Shouldn't the spaces be removed by makeSafe(), or not reported as an error?

Steps to reproduce the issue:

• Upload an image file with spaces in the filename to see the error.

Expected result

I expect the image file name to have the spaces removed, and the image uploaded.

Actual result

The image is not uploaded, and I get this error message:

Notice
File name must only contain alphanumeric characters and no spaces.

System information (as much as possible)

• PHP 5.3.29
• Joomla 3.4.3

Additional comments

The regex expression in /library/joomla/filesystem/file.php

$regex = array('#(.){2,}#', '#[^A-Za-z0-9._- ]#', '#^.#');

could be changed to this to remove the spaces:

$regex = array('#(.){2,}#', '#[^A-Za-z0-9._-]#', '#^.#');
