Short description of error
Crash while trying to replace materials in the material slot

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file
I have a relative complex object with several mateirals applied, with each mateiral assigned to a defined vertex Group, If I want to replace one specific material with another material (from within the "blender internal material stock"), blender crashes immediately, no matter whether with PBR shader materials or simple materials.

Philipp Oeser (lichtwerk) triaged this task as Needs Information from User priority.

Please share your blendfile here, so we can reproduce...

(this could be caused by a NormalMap node [see T56545], then this report would be a duplicate, but it is hard to tell without having access to your file...)

Marking as incomplete until this is provided...

Thank you, Philipp!
I have added the zipped blender file.


When saving the file, I left the astronaut's cloth in edit mode with some faces selected, in order to apply an additional material to these faces.
As soon as I am clicking into the material slot... boum, crash.
No idea, what's that...

I can not reproduce the crash with a build from today. Could you see if this problem still happens for you with a recent build?

I can reproduce the crash with rB6015a03255af. It's a duplicate of T56545.

@Martin Capitanio (capnm) : thx for checking, will merge the reports then...
