The *Messages* buffer should have something like this (.dvi or .pdf,
depending on whether you use dvipng or imagemagick):

Creating image...1
if: PDF file /tmp/orgtex31356_9l.pdf wasn't produced

If there is no such message, try diff'ing /tmp before and after you
try to produce the fragment. That should tell you the name of the .tex
file.

Try processing the corresponding .tex file from the command line:

  latex /tmp/orgtex31356_9l.tex

or 

  pdflatex /tmp/orgtex31356_9l.tex

and see where it breaks.
