[bug] org-create-formula-image-with-dvipng fails to find temporary file

[Maik Beckmann <beckmann.maik@googlemail.com>]

Hello,

Yesterday I've updated my git clone of org-mode after a few weeks of
not found time to.  I noticed the latex fragment preview (C-c C-x C-l)
broke.  I get messages like

    org-create-formula-image-with-dvipng: Removing old name: No such
file or directory, /tmp/orgtex17198KSG.out

Interestingly if another preview command is queued at the same the
same fragment that just failed, it works.  When run in a section
outside of any fragment, where previously all fragments in this
section would be rendered, it fails at the first run at the first
fragment, at the second run it renders it and fails at the second, at
the third run it renders it and fails at the third, and so on.

Just to be sure I've ran emacs -Q, evaluated (add-to-list 'load-path
"~/.emacs.d/org-mode/lisp") and opened a simple org file.  Same issue.

Right now I'm too short of time to dig into the code to figure out
what's going on, but I wanted bring it up anyways in case some of you
guys hit the same issue and search the mailing list for it.


Best,
Maik
