The .bin file has the correct contents.
I've tried altering the Content Type to application/x-upload-data, text/xml, application/graphml+xml but none of these changes anything, it's still .bin when downloading.
I just tried with two different browsers:
chrome Version 31.0.1650.63 (Linux) This one has the problem (editting a page, insert .graphml attachment, downloads as .bin file).
Firefox 26.0 (Linux) behaves somewhat differently. It asks me:
You have chosen to open:
which is: BIN file (167 KB)
Would you like to save this file?
If I click yes, I get the correct file with the correct extension
