Hi Jacques, There are reports about this already, (search for the error message). When manipulating Blender's state while rendering this can happen [1]
If you're not doing that, best narrow down the test-case and report a bug in our tracker: https://developer.blender.org [1]: https://twitter.com/tonroosendaal/status/370851236930539520 On Thu, Sep 10, 2015 at 9:17 PM, Jacques Lucke <[email protected]> wrote: > > > Hi all, > > while developing the animation nodes I get a specific error message > quite often in the console: "ERROR: Python context internal state bug. > this should not happen!" > > In the Blender source code this print statement is here: > https://developer.blender.org/diffusion/B/browse/master/source/blender/python/intern/bpy_interface.c$152 > > > What wonders me the most is that everything keeps working I just get > this error message in the console.
