I can confirm the bug under Linux for files in \special{PSfile=...}.
The problem is located in xdvipdfmx. Using the configuration
file dvipdfmx.cfg it constructs a command line for conversion to PDF.
The command line is then passed to the *shell* and the shell interprets
some characters in a special way.

I strongly recommend to change the D option of dvipdfmx.def
by adding single quotes around arguments with user input, e.g.:

  D "rungs ... -sOutputFile=%o %i -c quit"

to

  D "rungs ... '-sOutputFile=%o' -f '%i' -c quit"

Unhappily single quotes will not work in Windows, AFAIK.
At least double quotes can/should be used:

  D "rungs ... \"-sOutputFile=%o\" -f \"%i\" -c quit"

However double quotes aren't sufficient for Linux, because they
still allow the special interpretion of some characters.
