Did you try the parameter -k?

The user account doesn't matter since it's run as root.
Did you try "-s es" for testing?

Tried it out. Same result.

Not reproducible.
After you had this crash, reboot your system and have a look at /var/log/syslog,
it sounds more like a kernel panic than a BRLTTY-related problem.

Generally: Rename /sbin/brltty to something like /sbin/brltty.bin and then
write a script like this (with the name brltty):
#!/bin/sh
ulimit -c unlimited
/sbin/brltty.bin

And make it executable. If BRLTTY crashes, you get a "core.dump" in this
directory, which you can send to the list for further debugging.
