Comment (by mmarco):
The situation where i used it is in the singular interface.

It creates a text file called output, and tries to call "dot" on it. But
it fails, and creates an empty file output.jpg
With this new version, it creates the file output.jpg as expected.
Once you have the file output created, you can try to call dot manually on
it:

Once you have the file output created, you can try to call dot manually on
it, but if you don't have graphviz installed inside your sage
distribution, it will try to call the system wide binary. Even if it is
installed, it gives a segfault:
{{{
$ sage -sh
Starting subshell with Sage environment variables set. Don't forget
to exit when you are done. Beware:
* Do not do anything with other copies of Sage on your system.
* Do not use this for installing Sage packages using "sage -i" or for
running "make" at Sage's root directory. These should be done
outside the Sage shell.
Bypassing shell configuration files...
Note: SAGE_ROOT=/home/mmarco/sagedevel/sage
(sage-sh) mmarco@localhost:sage$ dot -Tjpg output -o output.jpg
segmentation fault
}}}
But with the spkg installed, it just creates the output.jpg file as
expected.
