Bug#518250: [nautilus] png files don't open - file type "png document" but contents of "PNG image"

[Jordi Burguet Castell]

Sure!

jordi at snow:~/downloads$ gcc test-mime-info-cache-new.c -o
test-mime-info-cache-new `pkg-config --cflags --libs gnome-vfs-2.0`
jordi at snow:~/downloads$ ./test-mime-info-cache-new
Default: gedit.desktop
All:
gedit.desktop, Text Editor
texmacs.desktop, GNU TeXmacs Editor
kde-qgo.desktop, qgo
abiword.desktop, AbiWord
emacs22-gtk.desktop, Emacs 22 (X11)
jordi at snow:~/downloads$


I have then downgraded shared-mime-info as you said (by editing
sources.list, changing "unstable" to "testing", then "apt-get update"
and "dpkg -r --force-all shared-mime-info", and finally "apt-get -t
testing --reinstall install shared-mime-info"... I am not sure if it
is the standard way).

It works! I can directly open the files. Nautilus is not showing
previews of most of the graphic files, though.

Thanks,
jordi
