Package: libgdk-pixbuf2.0-0
Version: 2.26.1-1
Severity: normal
Dear Maintainer,
It appears that some PNG files I used couldn't be load by
gdk_pixbuf_new_from_file,
because their mimetype was detected to be application/x-designer by
g_content_type_guess,
although the mimetype command returns image/png for these files.
These files can be viewed without problem with for example eog or gimp, but
can't be viewed
with geeqie.
The C program below returns
Mime: application/x-designer
test file load failure, error message: Couldn't recognize the image file format
for file '2-7.png'
The file 2-7.png is a proper PNG file but has a content that matches the magic
conditions
for application/x-designer in the /usr/share/mime/magic used by
g_content_type_guess.
Perhaps a solution to solve the problem would be to let GDK_PIXBUF_USE_GIO_MIME
undefined
(using gio_can_sniff=no in configure options?), but I don't know if this has
drawbacks.
Thanks,
AB.
