System Information
Win 10, Nvidia Gtx 730
system-info.txt

Blender Version
Broken: All Versions since 2.78
Worked: 2.77, 2.77a

I tested it with 2.77 to latest test build on two different systems (one with GTX 730, the Other with IntelHD). Some other users from a blenderchat tested it for me, too with the same result.
With Blender in debug mode (--debug fag) in cycles the console prints this error message when in texture display view and there are textured objects in the scene:
K:\BlenderGit\blender\source\blender\windowmanager\intern\wm_event_system.c:2575: ``wm_event_do_handlers'' -> GL Error (0x0502 - GL_INVALID_OPERATION): Invalid Operation
(the "c:2575 has a different number with different Blender builds, this one is from the Blender version in the attached system-info.txt)

Exact steps for others to reproduce the error

Start Blender with --debug
change to cycles
add a material to the cube
add a random image texture to the material
change to texture display view
on moving the object or changing viewport size etc. the error message appears (UV unwrap does not change it)

It does seem to make no harm (?) but i am developing an add on and since it segfaults on certain operations (with a high probability, not always) when in texture display mode (and not in solid display view) i wondered if there might be a connection to this error.

I can't reproduce this so far. Can you attach a .blend and image texture, to be sure there isn't anything different about what we are testing with?

I can reproduce it with an base material and an Image Texture like Color Grid attached to it on win 7 AMD R7 360 in Texture mode. Tested with build fee4b64, 2.79a RC.
Running with debug-gpu gives the following error:

C:\b\buildbot_vc2013_amd64\win64_cmake_vc2013\blender.git\source\blender\windowmanager\intern\wm_event_system.c:2636: ``wm_event_do_handlers'' -> GL Error (0x0502 - GL_INVALID_OPERATION): Invalid Operation
GL API error: glUniform1i has failed because the operation requires a currently active program object (GL_INVALID_OPERATION)

Sure, here is a blend.openglerror.blend
(texture is bundled, but in just in case...)
