 > I don't have imagemagick installed and I don't want to install it for
 just this ticket. What's your output of `./sage -t --optional=all
 src/sage/misc/latex.py` with the current branch (but without your
 changes)?

 There one long failed doctest, which I will abbreviate:
 {{{
 File "src/sage/misc/latex.py", line 1083, in sage.misc.latex.Latex.?
 Failed example:
     latex.eval("\ThisIsAnInvalidCommand", {}) # optional -- ImageMagick
 Expected:
     An error
     ...
     No pages of output.
     <BLANKLINE>
 Got:
     An error occurred.
     This is pdfTeX, Version 3.14159265-2.6-1.40.15 (TeX Live 2014)
 (preloaded format=pdflatex 2014.9.22)  8 JUN 2015 12:34
     entering extended mode
      restricted \write18 enabled.
      %&-line parsing enabled.

         [snip]

     <BLANKLINE>
     (./sage43.aux) )
     Here is how much of TeX's memory you used:
      2758 strings out of 493108
      34433 string characters out of 6134847
      90768 words of memory out of 5000000
      6200 multiletter control sequences out of 15000+600000
      4403 words of font info for 15 fonts, out of 8000000 for 9000
      1141 hyphenation exceptions out of 8191
      38i,1n,26p,260b,38s stack positions out of
 5000i,500n,10000p,200000b,80000s
     <BLANKLINE>
     No pages of output.
     PDF statistics:
      0 PDF objects out of 1000 (max. 8388607)
      0 named destinations out of 1000 (max. 500000)
      1 words of extra memory for PDF output out of 10000 (max. 10000000)
     <BLANKLINE>
     <BLANKLINE>
 **********************************************************************
 1 item had failures:
    1 of   2 in sage.misc.latex.Latex.?
     [308 tests, 1 failure, 12.37 s]
 ----------------------------------------------------------------------
 sage -t src/sage/misc/latex.py  # 1 doctest failed
 ----------------------------------------------------------------------
 }}}
 So the issue is the extra lines starting "PDF statistics", plus two
 `<BLANKLINE>`'s at the end instead of one.
