System Information
Archlinux

Blender Version
Broken: 5cd3212

Short description of error
There are really three bugs, but they seemed related so I thought I would put them all here.

1.
Selecting a material in the drop down under Particles > Render with the particle type set as an object does nothing. The material of the instanced object is used, even if undefined.

2.
When pinning a properties panel to display only the particle system, the material which is displayed in the drop down as "selected" changes as the emitter or the instanced particle object is selected.

3.
The drop down only lists materials that are in material slots of the emitter object.

Exact steps for others to reproduce the error
Based on particle_bug.blend

Bug 1:

Open attached file
The particle material drop down will be set to the "Emitter" material (blue), however the actual particles will be displayed as the "Particles" material (red).
Select the particle source object (the higher cube) and remove the material. The particles will display as the default gray.
Select the emitter cube again. The drop down says they are using the "Emitter" material, however they never were.

Bug 2:

Open attached file
Select the particle source object (the cube that is higher up) while watching the material drop down in the pinned particle system panel. The material displayed as selected will change.

Bug 3:

Open attached file
Select the higher up cube and create a new material
Select the lower cube and open the particle material drop down. The newly created material will not be listed.

There is absolutely no bug here… the "Material" option of the particles only affects "usual" particles. When objects are duplicated as particles, it is obviously their materials that are used!

Will just disable that mat dropdown when Object or Group render types are selected…

Ah, my bad.

What about bugs 2 and 3? They still occur in c7ac0ed even though the drop down is now disabled (3 only occurs when a different particle type is selected, of course).

is not a bug! Particles use material slots, not directly materials themselves… So you only can use materials assigned to one of the emitter’s slots.

Point 2) is indeed an issue (material slots are referenced by their index, when active object changes, I guess this is the issue). Will check this.

3) is not a bug! Particles use material *slots*, not directly materials themselves… So you only can use materials assigned to one of the emitter’s slots.

Bastien Montagne changed title from ~~Material selector for particles does nothing~~ to Wrong material reported in particles settings when pinning them and selecting another object.

I fixed this bug without noticing it was assigned already, sorry about that, hope you didn't work on a fix yet.

brecht:
In your commit I see you change this
RNA_def_property_ui_text(prop, "Material Slot", "Material slot used for rendering particles");
for this
RNA_def_property_ui_text(prop, "Material Slot", "Material nlot used for rendering particles");

"nlot" instead "slot"
