Unable to load image-loading module: /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.so

[Hadmut Danisch]

Hi,

I am using a commercial image processing program named bibble5, which was working well for more than a year under ubuntu. After upgrading ubuntu to 11.04, bibble5 crashes when run under the 64 bit version of ubuntu (still works with the 32 bit version of ubuntu).

The last (and abnormal) lines bibble5 prints on stderr are:

/usr/lib/gio/modules/libgiobamf.so: wrong ELF class: ELFCLASS64
Failed to load module: /usr/lib/gio/modules/libgiobamf.so
/usr/lib/gio/modules/libgvfsdbus.so: wrong ELF class: ELFCLASS64

Segmentation fault

So it looks as if there was a severe problem between the gimp libraries and librsvg, introduced with Ubuntu 11.04, which occurs only on the 64 bit version.

Is anyone out there taking any notice of this bug?

[Andrew (andrew-rw-robinson)]

Note that firefox 3.6.17 has the same issue. The problem is that the 32-bit application is picking up a 64-bit shared library.

Probably need to see if there is a package that provides that so file as 32 bit on ubuntu 64

[Hadmut Danisch (hadmut)]

Yup, seems so. Bibble5 starts as a 32-bit program and uses it's only Qt libraries that it brings with. These start to load 32bit gtk stuff from /usr/lib32 , which then somewhere loads from /usr/lib/gtk-2.0 and thus starts using 64 bit libraries.

I still see

4126 open("/usr/lib32/libgtk-x11-2.0.so.0", O_RDONLY) = 17
4126 open("/usr/lib32/libgdk-x11-2.0.so.0", O_RDONLY) = 17
4126 open("/usr/lib32/libpangocairo-1.0.so.0", O_RDONLY) = 17
4126 open("/usr/lib32/libXcomposite.so.1", O_RDONLY) = 17
4126 open("/usr/lib32/libatk-1.0.so.0", O_RDONLY) = 17
4126 open("/usr/lib32/libcairo.so.2", O_RDONLY) = 17
4126 open("/usr/lib32/libgdk_pixbuf-2.0.so.0", O_RDONLY) = 17
4126 open("/usr/lib32/libpangoft2-1.0.so.0", O_RDONLY) = 17
4126 open("/usr/lib32/libpango-1.0.so.0", O_RDONLY) = 17
4126 open("/usr/lib32/libpixman-1.so.0", O_RDONLY) = 17
4126 open("/usr/lib32/libxcb-shm.so.0", O_RDONLY) = 17
4126 open("/usr/lib32/libxcb-render.so.0", O_RDONLY) = 17

which are 32bit

but then

4126 open("/usr/lib/libgnomeui-2.so.0", O_RDONLY) = 17
4126 open("/usr/lib/libgnomevfs-2.so.0", O_RDONLY) = 17
4126 open("/usr/lib/liboverlay-scrollbar-0.1.so.0", O_RDONLY) = 17
4126 open("/usr/lib/gtk-2.0/i686-pc-linux-gnu/modules/libcanberra-gtk-module.so", O_RDONLY) = 17
...
4126 open("/usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so", O_RDONLY) = 18

so there is somewhere a problem with the gtk/gdk libraries suddenly jumping from 32 to 64 bit.

[Hadmut Danisch (hadmut)]

Seems to be a bug of the ia32-libs package.

Although the 32-bit libraries can be found under /usr/lib32 , some libraries under /usr/lib32 load further libraries from /usr/lib , so it looks as if not all libary file system paths have been adjustet to use /usr/lib32 instead of /usr/lib.

[Hadmut Danisch (hadmut)]

OK,

I found the precise reason for the problem and two methods to workaround.

See my bug #781870
