problem exporting latex fragments to html: Debian's dvipng 1.12-1 is buggy

[Eric S Fraga]

Hi,

I'm obviously having a bad two days with org-mode but, this time, I've
actually solved the problem myself.  I thought I would highlight the
issue in case anybody else runs into this.

Short summary: exporting org files with latex fragments to HTML failed
to create the images.  I tracked the problem down to dvipng failing
(memory reference problems).  My system is Debian with a mixture of
testing and unstable (yes, this will do it to you every time!).  In
any case, version 1.12-1 of dvipng seems to have problems; the latest
in testing is 1.12-3 and this one works.

However, I thought I would bring up a minor point: the failure to
create images was not obvious; I had to resort to going through my
*Messages* buffer.  I then tried toggling debug on error to see why
the image creation was failing but this had no effect as an error
condition is not raised; this begs the question: should an error
condition be raised when an image creation fails?

Thanks,
eric

Hi Eric,

OK, this now throws an error.
