--- Comment #1 from Tapani Pälli <lemody at gmail.com> ---
For me it seems this behavior is according to the OpenGL ES spec:

"An INVALID_OPERATION error is generated if the level base array was not
specified with an unsized internal format from table 8.3 or a sized internal
for-
mat that is both color-renderable and texture-filterable according to table
8.10."

Table 8.3 does not list GL_RED.
