This does not seem to solve yet.
Bone rolls 60 degrees and re-calculated by the Global Z Axis.
In addition to roll several times and pushing out the Z-axis direction while holding down the CTRL.

Procedure that I have run.

1.Create Armature.
2.The change in the B-Bone Armature type.
3.In the Edit mode.
4.Recalculation (Global Z Axis) the Bone roll.
5.Bone roll is changed to 60 degrees.
Is this correct?

Next.
1.Create Armature.
2.The change in the B-Bone Armature type.
3.In the Edit mode.
4.Extrude.
5.Dragging vertically while holding down the CTRL.
Bone rolls many times.

@sindra1961 - please give more detailed bug reports in future.

You raise 3 unrelated issues in very short report, and don't provide a blend file.

@mont29 - you know of the issue extruding a bone on Z axis causing the roll to flicker and change values erratically?

I always feel that I am sorry about incomplete things reporting.
I prepared two blend files.

roll1.blend
Recalculation of bone roll is not right.
In the case of Global Z Axis, it is set to 60 degrees.
In the case of Global Y Axis, it is set to 180 degrees.

roll2.blend
Roll is changed many times you move while holding down the CTRL vertically bone that is extruded.

re: roll1.blend

This isn't a bug.

Global Z Axis: Your trying to align the bone to an axis which doesn't really make sense.
Global Y Axis: Works correctly, enable Bone Axis, and you can see the bones +Z axis is aligned to the global +Y axis. If you don't want 180d rotation you can enable Shortest Rotation option.

Global Z Axis could behave differently (ignore alignment when the bones are orthogonal to the axis). but in this case getting the threshold right is tricky (and could even give problems where some bones align, some not as they reach the threshold), so I prefer to leave as-is.

I had always understood Global Z Axis is it synonymous with clear roll of 2.49b, but do you say it is wrong?

http://wiki.blender.org/index.php/Doc:2.6/Manual/Rigging/Armatures/Editing/Properties

Because an official document is not maintained for 2.6, I do not know it what is right.

I'm sorry, I noticed a mistake.
I forgot to have always made it in Up-Y.

The report about roll1.blend was my misunderstanding.
I'm sorry.

Phenomenon of Roll2.blend weird.
You may not reproduce it when you move the bone of children Roll2.blend.

It does not seem to reproduce the position of the bone that extrusion become clearer.
No problem still move vertically bone after it was determined the position of the bone which extruded.
However, to reproduce when you move vertically to cancel the determination of the position.
it is reproduced immediately after extrusion the bone.

This phenomenon seems to only occur significantly If you drag the mouse while holding down the CTRL.
In the case of free drug even occur from time to time when you move vertically bone.

I add a Roll3.blend file.
This are recalculated in Global Z Axis the parent bone.
Roll also this if you drag it by extruding the child bone anew.

Can confirm the 'Z scale' roll issue is back (though less bad than in its previous versions)… :/
