guvcview exported jpeg file incorrect

[Andrew Kay]

I have a logitech C920 webcam, and Kubuntu 14.04LTS, arch x86_64

png files are saved correctly.

When I try to save a snapshot image with guvcview in jpeg format, the file is malformed

(specifically, gwenview says

"gwenview(29407) Gwenview::JPEGErrorManager::errorExitCallBack: Quantization table 0x00 was not defined
gwenview(29407): libjpeg error in src"

but I can't open the file in irfanview either, so I think it is the file that is at fault.)

steps to reproduce:
start guvcview
go to menu photo>>file, and choose jpg file output
in main panel click "cap. image"
quit guvcview and attempt to open image file.

expect: to see image
actual: image will not load (incorrect format)

Yes, I have the same problem. All files was made by guvcview as: guvcview_image-1.jpg, guvcview_image-2.jpg,... cannot open with any image/photo viewer software. They corrupted or incorrect format? I attach an example JPG file.
