%%%--- Operating System, Graphics card ---
Linux Mint 14
GeForce 9800 GT

- Blender version with error, and version that worked ---

The bug is in SVN r54196
It doesn't exist in 2.65a

- Short description of error ---

Custom shapes on an armature, when linked into a scene with the "At" field set for the custom shape, have their transforms reset when CTRL-Z is pressed.

Basically, if you are using another bone to position a custom bone shape, this seems to be reset as soon as CTRL-Z is pressed. The problem only seems present when the armature is a proxy. The problem also seems to depend on which bone was selected when the file was saved.

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

In the attached zip file are 2 blend files. Open "linked_rig.blend", select "Bone.002" (the top right bone) and rotate it. Press CTRL-Z. The sphere widget snaps to another position.%%%

%%%I managed to find a fix for undo in proxy posing, it always went to restpose before (so 2.65a didn't "work" either :).
Will check on the examples here for custom bones.%%%

%%%I'm not sure if it helps, but the problem came up on the FlexRig.
The widgets for the hips, spine and torso get relocated when undoing anything in the latest SVN. (But only when it's linked)

%%%Hi Ton,
Sorry to bug you about this, but what is the chance that this will be fixed before the next release?
If it wont be, we're going to have to send out a warning email to our customers and users.%%%

%%%Confirmed on my machine.

This breaks the usability of pretty much every rig I've made in Blender 2.5x+, including:

All of the rigs from Sintel
All of the non-trivial rigs in Humane Rigging
Almost any rig generated by Rigify
The FlexRig from the Animation Toolkit

This is a serious bug. Technically you can still use rigs with it, but in practice rigs are rendered very difficult and confusing to use.%%%

%%%Fix goes go svn. r54351

It was actually a bug in the original commit (r26600, april 2010), storing a pointer from the library bone into the local proxy.
That's strictly forbidden in Blender, but it never showed up because on every undo-redo a complete proxy-sync was called again. To allow undo/redo I had to disable this obsolete syncing, except for file load. Hence the feature got lost.

Mighty cool that it's such a simple fix, or rather - that I still understand the code ;)%%%
