I got a DSK file from other user which works fine on their system,

I don't know if this is a bug in SIMH on my linux (suse 11.3 64bit on
amd phenom-ii quad-core)
or something I'm doing wrong, but the most recent error is the 2nd one,
which seems to indicate a fatal bug in simh, this is in the latest
code version I could download of simh...

Just some thoughts that fly by in reading you post:
From the mailed .INI-file, the commands set up rq0 as a CD with an
attached .ISO-file.
Then you try to boot from this "CD".
Q1: Should the 780-emulator be able to recognize a CD as a device? - In
those days the TU58 was "the media" for console works...
Q2: If this booting is proper after all, and the file you have attached
to the rq0 is the boot-disc you intend to use, should it really be
attached to a "read-only" device like a CD, not to a disc? - I know
later systems can boot from a CD, but doesn't that require booting a
system image that is tailored to this task - i.e. that doesn't require
any dump-files or similar?
(You say that the emulator reads your .DSK properly, but to my eyes does
it only read the file vms6_0.iso, ie the CD-immage).
All my best anyhow - every effort to maintain this generation of systems
indicates a great spirit!
