System Information
Kubuntu 14.04 64bits, Intel i7, Nvidia GTX560

Blender Version
2.70a (f93bc76)

Short description of error
When modifying a value of a noise modifier, for an animation channel of a BONE in Graph Editor (F-curves), the modifier's panel disappear, as if you deselect the channel. This happen only if the affected animation channel is not in first position.

Exact steps for others to reproduce the error

load factory settings
delete default cube
add an armature > single bone
switch to Pose mode
insert a keyframe
go to Graph-editor, F-curve context
select the second (or later, but not the first) animation channel in the (left-hand) list
expand properties panel, and add a noise modifier

try to slide some value of the noise modifier. It disappear, and all the animation channels are selected.

Also note that on objects animation channel, it works well. It seems to only affects bones in pose mode.

Aha... it seems to only happen when the dopesheet is also open when doing this. So the workaround for now is to simply keep the dopesheet closed if/when you're editing the curves (which I highly recommend in general anyway; not sure why all the workspace layouts out there keep trying to do this, but it's not such a great idea)
