Here is the rub:

prv_Nachrechnung is a predumped format containing the preamble, dumped
by using mylatex.ltx.

Normal.  And everything looks normal up to here:

Fine till here.

But now:

And so on. Instead of an output file name, here is an empty string.
In my comparable test, there is

Running `Preview-Ghostscript' with ``gs -dOutputFile\=\(junk.prv/tmp5246ebu/pr1-\%d.png\) -q -dSAFER -dNOPAUSE -DNOPLATFONTS -dPrinted -dTextAlphaBits\=4 -dGraphicsAlphaBits\=4 -sDEVICE\=png16m -r132.114x132.241''

So you are doing something that messes up the file name generation of
GhostScript within preview-latex.  I have no idea what would do that,
and doing a proper bug report with the intended commands to the proper
channels might help pinpointing this.
