Hi,
In the Gnus trunk and the Emacs trunk, I updated a header format
that Gnus passes to the icontopbm program when displaying X-Face.
That was:
/* Width=48, Height=48 */
Now it is the same as what pbmtoicon returns:
$ pbmmake 48 48| pbmtoicon| head -2
/* Format_version=1, Width=48, Height=48, Depth=1, Valid_bits_per_item=16
*/
The most recent icontopbm[1] requires it:
$ icontopbm --version
icontopbm: Using libnetpbm from Netpbm Version: Netpbm 10.54.4
icontopbm: Compiled Sun, Jun 19, 2011 17:09:54 by user "Yaakov"
icontopbm: BSD defined
icontopbm: RGB_ENV='RGBDEF'
icontopbm: RGBENV= 'RGBDEF' (env vbl is unset)
$ echo '/* Width=1, Height=1 */ 0x0000'| icontopbm
icontopbm: invalid sun icon file header: only 2 out of required 5 fields present
$ echo '/* Format_version=1, Width=1, Height=1, Depth=1, Valid_bits_per_item=16 */ 0x0000'| icontopbm

I verified that's also ok for old ones (tested with Netpbm 10.35.58
of June 1 2009, and 10.47.25 of January 18 2011).
Recently I updated Cygwin on the office PC and noticed this.
