%%%OS: Linux - Ubuntu 10.04 64bit
Build: 34414

In the attached file there's an armature with one bone in layer 4. That bone has a nested IDProperty (xplane.datarefs- [x].value). When trying to add a keyframe to the nested property blender crashes with a segfault. Maybe something with resolving paths? I've tried adding keyframes to regular custom props of a bone and found out that after renaming the prop the fcurve becomes invalid as it seems to be bound to the prop name. Also I've seen that the fcurves are actually added to the armature, not to the bone, as bone don't have fcurves?%%%

%%%Forgett to mention:

I'm using Bone.xplane.datarefs- [x].keyframe_insert(data_path="value",group="XPlane Dararefs "+bone.name).
Bone.xplane.datarefs- [x].value is a FloatProperty
Bone.xplane.datarefs- [x] is a PropertyCollection%%%

%%%This bugreport is not clear enough

How are you getting "Bone"? Bone = bpy.data.armatures["Armature"].bones["Bone"], OR Bone = bpy.data.objects["Armature"].pose.bones["Bone"], OR something else?
Where are you running this line from? Console? A Script?

For ease of testing/repeatability of the bug you're getting, if you're running commands from py, then set up the file with a script that runs the offending commands, and then upload that file so that we can just run the script to test (instead of guessing how you're doing this).

Also, it seems odd to be adding properties on Armature/restpose level of bones instead of Pose level. Pose level is where most settings such as transforms and stuff animators can tweak go...%%%

%%%der On, can you explain how to redo this crash, from looking at your file there are no scripts which setup these properties.

It should be possible to make a file where 2-4 steps can redo this crash.%%%

%%%Hi, looked into this file, it now complains the properties are not set,

Traceback (most recent call last):

File "activate", line 5, in <module>
File "/data/src/blender/blender/release/scripts/modules/bpy/ops.py", line 179, in __call__
  ret = op_call(self.idname_py(), None, kw)

SystemError: Calling operator "bpy.ops.export.xplane_obj" error, could not be found

The script needs to define the RNA, this would be currently be being done by your addon.%%%

%%%Instead of segfaul blender now throws a RNA error. One leap forward. Thanks.

Tried adding those nested properties to PoseBones now and then adding keyframes but this was giving me the same error as with the props@bone.%%%

%%%looked further into supporting this, its basically impossible unless the PointerRNA stores a reference to its parent.
because its possible that the rna exists but the ID property data doesnt. if the struct is used twice there is no way to know which one we are looking at.

moving to todo.

for now you can add an fcurve to animdata directly and set its path.%%%

%%%Ok, got that adding fcurve manually but how would that path look like?

At the moment I'm trying to attach properties to the poseBones and create data paths that look like this:

pose.bones[index].xplane.datarefs[index].value (this causes blender to crash when trying to expand the created Action-Group in Curve-Editor, my Property won't update in UI)

Also tried: PoseBone.xplane.datarefs[index].value (no crash, nice fcurve, but my Property won't update in UI)%%%
