Yes, this is a known issue.  At present, Guile must be fully initialized
in one thread before it can be safely used from any other thread.
Furthermore, when loading modules, you must ensure that no other thread
attempts to load or use the same module while it's being loaded.  If
possible, please arrange to load all modules that your program will need
before accessing Guile from other threads.

We'd like to fix this at some point, but for various reasons it's a
non-trivial project.

     Thanks,
       Mark
