  The reason is very simple: recent versions of imagemagick write
stupid resolution information to the JPEG files (such as 1 dpi), so
you end up with very very large image (several meters large !), and
latex just gives up.

  While I agree this is clearly a problem with imagemagick, it is also
a bug in LaTeX.

  A simple workaround is the following: add a -density 75 option
before the output in convert:

  convert bad_jpeg.jpeg -density 75 latex_friendly_jpeg.jpeg

  Cheers,

  Vincent

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Package: imagemagick
Version: 8:6.8.9.6-4
Severity: important

The current version of imagemagick (and its library used by gkrellshoot)
creates jpeg images that cannot be used in pdflatex with graphicx
anymore.

There is already a bugreport in redhats bugzilla[0].

[0] https://bugzilla.redhat.com/show_bug.cgi?id=1086715

To have the informations also in this bug, this is the result I have
seen (Only relevant part):
- --- input.tex
...
\usepackage{graphicx}
...
\includegraphics{gkrellShoot_}
...
- ---

- --- Output
...
pdfTeX warning: pdflatex: arithmetic: number too big


pdfTeX warning: pdflatex: arithmetic: number too big


Overfull \hbox (67.0553pt too wide) has occurred while \output is active
 [][]  \T1/cmss/m/sc/6 ([])  
...

Other formats like png does work correct.

Severity disclaimer:
I filled that bug as important as I see it very important for the
package functionality. However, it might be between normal and important
so feel free to lower if you want.
