it has worked before opening and displaying a file like this, anything
to do with python 2.52, upgraded from 2.5.1

Did it work with that exact file? Have you tried other files that did
work with 2.5.1? The error comes from tcl/tk, not Python. I expect
that the version of tcl/tk delivered with 2.5.2 is exactly the same as
that delivered with 2.5.1, just to avoid such problems.

Note that even if one program displays a file it may still be slightly
corrupt and properly fail to display with another. If you have an image
editor, you might try opening and saving (different name) without changing.

Did it? Because AFAIK, tcl/tk has never natively recognized any other
image format than PPM/PGM and GIF... No JPG, no PNG...
