Hmm, that seems to be because:
...
(gdb)
#5  0x0000000000a59a7c in gdbpy_handle_exception ()
     at /home/vries/gdb_versions/devel/src/gdb/python/py-utils.c:396
396             error (_("Error occurred in Python: %s"), msg.get ());
(gdb) p msg.get ()
$1 = 0x2b91d10 "module 'queue' has no attribute 'SimpleQueue'"
...

That's new in python 3.7, and I have:
...
$ ldd ./gdb | grep python
         libpython3.6m.so.1.0 => /usr/lib64/libpython3.6m.so.1.0 
(0x00007f93ed624000)
...

Thanks,
