Can't open JPG files - bad module?

[MDguy]

While trying to install Cinelerra on Ubuntu 10.10, I copied/moved around some of the .so modules located under /usr/lib. Now I find that I cannot open JPG images - Image Viewer will give me the following error (see screenshot):

Unable to load image-loading module:/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-jpeg.so: /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-jpeg.so: undefined symbol: jpeg_resync_to_restart

Attempting to open the image with GIMP will give me (see screenshot 2):

GIMP Message
Plug-in crashed: "file-jpeg"
(/usr/lib/gimp/2.0/plug-ins/file-jpeg)

The dying plug-in may have messed up GIMP's internal state.
You may want to save your images and restart GIMP to be on the safe side.

GIMP message

Opening '/usr/share/backgrounds/Crocosmia_by_sirpecangum.jpg' failed:
Procedure 'file-jpeg-load' received no return 
values.

PNG files will open fine.

Any assistance would be appreciated!

Try searching for the module and put it back in /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders/

sudo find / -name libpixbufloader-jpeg.so

Thanks for the reply, but when I looked I saw that the module is actually still there - perhaps it's corrupted?

EDIT: I obtained a copy of libpixbufloader-jpeg.so from the LiveCD and replaced the current module with new one, but I'm still getting the same error message.

How about reinstalling Gimp?

I'm fairly sure it's not a GIMP problem, since the images won't open with ANY image viewer/editor that I've tried.

I am also finding that certain programs such as Filezilla and Ubuntu Software Center will not open because of this problem. If I type "filezilla" into the terminal, I get:

filezilla: symbol lookup error: /usr/lib/libtiff.so.4: undefined symbol: jpeg_resync_to_restart

I'm not convinced your problem is with libpixbufloader-jpeg.so. I'm not an expert in this, but the origina messagel is ambiguous, it may be telling you that libpixbufloader-jpeg.so can't be loaded because it references a "jpeg_resync_to_restart" symbol than can't be found.

You may be missing something a bit further downstream, such as libjpeg.so. If this is the case, you can also try to deinstall/resinstall it.

Okay, I downloaded libjpeg-8b from this site, and after installing it, I am getting this error:

It seems to have done something related to the problem, but still didn't repair it completely.
