It is very strange that I can't reproduce, if this is the cause,

Actually, all my files are converted correctly. But using the one
attached to the bug report triggers reproducibly the behavior.
Not that I get converted files which are always mangled in different
ways, which is a symptom of a race condition. Also, I have some large
files (~ 700k) that convert flawlessly. So, the bug also depends on
the structure of the document, somehow.
I think I found the explanation why this document triggered this bug.
The document makes heavily use of macros _and_ the macros are in view
after the document is loaded. This causes the metrics computation for
the macros to run while exporting the document. The function
MathMacroTemplate::metrics() makes use of FontSetChanger, which is the
reason why we see all those fontset-strings in the corrupted document.
