raiseIOError in python lib ImageFile.py: "image file is truncated"

It's crashing because the ImageMagic library isn't able to process the image you've uploaded to the server. It says that it's been truncated which likely means the upload failed.

Try uploading the image to the server again and see if that improves things.

The client could handle that better. I'll file a bug,

Thanks for your answer, but I tested it with several image sizes and formats, deleting and uploading images to the server, and keeps giving the same error:

File "/usr/lib/python2.6/dist-packages/PIL/ImageFile.py", line 201, in load
    raise IOError("image file is truncated (%d bytes not processed)" % len(b))
IOError: image file is truncated (14 bytes not processed)

Am I the only one that gets this error?

Can you check in the data directory that the image files are downloaded properly and open with GIMP or similar?

If they do open okay, please can I have a copy of one of these images so I can see for myself?

I've not seen this error in the wild before.

Alex

Sure, I tried with these images: http://www.mathworks.com/matlabcentral/fx_files/21944/2/DancingPeaks.gif
and a light image that shouldn't give any problems: http://www.etoncollege.com/UserFiles/Image/Eton%20Blue.jpg

When uploaded, I set these images as background of the layout.
And yes, images are downloaded properly and not corrupted, I can open them with GIMP. It seems it happens with any image.

I put both those images as the background on a layout on a 1.2.2 client and they work fine - no errors.

You do have at least one region on your layout with something in it don't you?

So for example the layout I created had one region on it with some text in it, and the images you describe as the background image.

In Xibo, every layout must have at least one region and that region must have a media item in it.

This is odd. This time I added a region with some text and a image, and still having the same problem:

This may give some more info. When I set none as background image, it prompts:

Original exception was:

But at the second time I typed ./run.sh, it prompted the same as always. Furthermore, I'm unable to stop python process by killing it as sudo, I just doesn't stop:

 1386 pts/0 Sl+ 0:03 /usr/bin/python XiboClient.py

So I have to restart my computer to stop the process
