System Information
AMD X3 455, R7 360, Win7

Blender Version
Tested on: 2.67b, 2.70a, a6ca8a1, 4d8ac1e (windows only sorry i didn't test it on linux this time)

Short description of error
Memory leak when adding a new image in the UV/Image editor, with the T panel (image analysis tools Vectorscope and friends active) and Undo
Examples of the cmd prints:

Error: Not freed memory blocks: 4, total unfreed memory 7.421875 MB
waveform point channel 1 len: 972800 0000000019A80CB8
waveform point channel 2 len: 972800 0000000012B80B88
waveform point channel 3 len: 972800 0000000027BC00B8
vectorscope point channel len: 972800 0000000021370048

Error: Not freed memory blocks: 4, total unfreed memory 5.750000 MB
waveform point channel 1 len: 753664 000000000D2C4B48
waveform point channel 2 len: 753664 000000000D37CB98
waveform point channel 3 len: 753664 000000000D434BE8
vectorscope point channel len: 753664 000000000D4ECC38

Exact steps for others to reproduce the error
Start blender with -d --factory-startup from command line> go to the UV Editing screen layout> make the T panel active (so the image analysis tools are open)> add a new generated image (it seems that doesn't matter if the image is pure black or not) press ok so the image is now in the editor> press Undo so the image is removed from the editor> quit Blender

The errors seems to appear also on image renaming, and seems to compound the leak grows up in size if the several undo operations are done.
