System Information
Ubuntu 14.04 64 bits - GTX 860M

Blender Version
2.73a

Short description of error
Mirror bones during rigging fails

Exact steps for others to reproduce the error

Open .blend file
In edit mode, select all bones
Duplicates all bones ( Shift+D), and move somewhere else
Flip Names (W)
Invert selection (Ctrl+I)
Move bones (G + enter, without any moves, only to mirror new bones)
- Constraints are not set up correctly

(Sometimes, with more complicated rigs, parenting are not set up correctly too. Will provide a .blend when I will find most simplified rig with this error)

Don't hesitate to contact me if you need more information.

It looks like automatic naming of bones is wrong.

While duplication, the bone in middle of chain is called parent.L.003 instead of parent.L.004 which is at start of duplicated chain.

Flip Names operator on a corrected ordered chain is also breaking the order by doing same thing.
But it looks like being more devastator by deleting all constraints on armature.

There is no problem, if each bone of duplicated chain is renamed individually.

I think there is no issue here either - duplicating the chain like that will create new bones with different names. Maybe an operator to create a duplicated armature with flipped names might be a nice solution but duplicating first and flipping later is not going to work.

Hello,

What is weird here is that new bone names are not following same order than original bones. For example, Bone, Bone.001 & Bone.002 will be duplicated in Bone.003, Bone.005 & Bone.004.
I think "sorting" correctly bones during duplicating process can solve the issue.
Never mind, I'm developing a python operator that do it correctly.
Thanks :)

Hello,
