I have to correct my first mail.
Of course, the file descriptor is write-only, not read-only.

First a fine ISO image gets written and then the multi-session
mechanism kicks in unprepared. It overwrites the first 64 kB
with zeros. 
I have now identified the immediate reason and committed a
remedy as rev 4078. See

The code change only applies to write-only targets which seem
to be quite unsuable currently. So it is of low risk.
On the other hand i still have to study its exact consequences
and i will have to check the code for similar occasions.

So it might last a few days before libisoburn-1.1.2 gets released
with a bug fix.

Have a nice day :)
