System Information
Win7 64bit, NVidia Quadro 2000

Blender Version
Broken: 2.69 (newer versions as well)

Short description of error
Clicking on the "Open Shading Language" checkbox in the Render settings (Cycles), packed textures are not loaded any more during rendering, and the materials are shown in pink. There is no feedback or error message why this happens.

I had this with a new user, where the troubleshooting took several hours(!), until we had found that disabling OSL brings the textures back. It was probably accidentally enabled earlier during the project, didn't change anything, it was left on, until one day a material with a packed texture was added.

Exact steps for others to reproduce the error

Turn on cycles.
Add a new material, enable nodes, add an image texture to the colour input, add any mapping type.
Pack the textures (File -> External Data -> Pack into .blend file)
Render => Works
Enable Open Shading Language in the render settings.
Render => Pink render, texture is missing.

Packed textures are only supported for non-OSL. This is because OSL uses OIIO directly and there's no clear way to pipe memory buffer there. And even if there was a way to open image from memory using OIIO you'll need to implement own filtering functions.

This is a nice feature to support, but not considered a bug.
