When using any sort of multiple select operation (e.g., select all, band select, lasso select), the graph editor does not populate the left panel with channels. However, the graph view itself is populated with key handles, and it is possible to manipulate them.
Shift-selecting any of the bones in the selection will force the graph channel list to properly populate.
The video below shows the issue:

I'm able to reproduce this with a minimal set-up as well. It seems to be triggered by having any other object in the scene, but I can't be sure what is actually causing it.
Another oddity. The bug does **not** manifest if you already have a bone from the armature selected. It only seems to occur if no bones are selected at all.
**Exact steps for others to reproduce the error**
1. Add an Armature object to the scene.
2. Add a Location & Rotation keyframe to the sole bone.
3. In pose mode, use "Select All" (A). Note that the channel panel is correctly populated.
4. Add an Empty object to the scene.
5. Select the armature again and enter pose mode.
6. Deselect the bone.
7. Use "Select All" (A) to select the bone.
8. Note that the channel panel does not populate!
