Downgrade to 1.9.8-4 to fix.

Same on my system. I think it might have something to do with jack2 expecting a firewire driver? For I get:

Could not open component .so '/usr/lib/jack/jack_firewire.so' : libffado.so2: cannot open
shared object file: No such file or directory
jack_get_descriptor : dll jack_firewire.so is not a driver
Segmentation fault (core dumped)

There is no firewire interface on my computer.

I got the same error as creatid. I installed libffado (which is an "optional" dependancy) and everything works fine now. I think the new jack2 may mandatorily depend on ffado, but the JACK website doesn't mention such a thing.

Whats weird is that the old version displays practically the same error message but doesn't crash:

jack2-1.9.8-4:

could not open component .so '/usr/lib/jack/jack_firewire.so': libffado.so.2: cannot open shared object file: No such file or directory
could not open driver .so '/usr/lib/jack/jack_firewire.so': libffado.so.2: cannot open shared object file: No such file or directory
jack_get_descriptor returns null for 'jack_firewire.so'
could not open component .so '/usr/lib/jack/jack_firewire.so': libffado.so.2: cannot open shared object file: No such file or directory
JACK server starting in realtime mode with priority 10

[goes on to run succesfully]

jack2-1.9.9.5-1:

Could not open component .so '/usr/lib/jack/jack_firewire.so': libffado.so.2: cannot open shared object file: No such file or directory
Could not open component .so '/usr/lib/jack/jack_firewire.so': libffado.so.2: cannot open shared object file: No such file or directory
jack_get_descriptor : dll jack_firewire.so is not a driver
zsh: segmentation fault (core dumped)  /usr/bin/jackd -v -dalsa -r44100 -p1024 -n2 -D -Chw:Lambda -Phw:Lambda -i2 -o

I can't tell if not having libffado as a mandatory dependancy is the problem of if its a problem with how jackd acutally handles not finding the FireWire (ffado) library.

EDIT: I use a USB audio interface, not a FireWire one, so I had it working fine without libffado before the upgrade.

I'd rather not clutter my system with redundant libraries for interfaces I don't even have in my system.
The package page states libffado is optional and since 1.9.8 worked without it, it appears to be an error in the package.
