There was a mistake: read 'foo.png.bzip2' == 'foo.png.bz2' in the above text.

Here both foo.png.bz2 and foo.png.bzip2 produce almost the same result: only 
'garbage' is displayed, not the PNG image.

Anyway, the .bz2 version is decompressed but not the .bzip2. I have checked 
this also with a text file: foo.txt.bz2 is displayed correctly a fully 
readable; foo.txt.bzip2 is displayed as 'garbage' (should have seen .bzip2 
files somewhere...).

BTW, I tested this both on Windows build and GNU/Linux (cairo build).

If this is to be expected, it is useless to file a bug report.
