Package: phosh
Version: 0.4.3-1
Severity: grave
Justification: renders package unusable
Hello,
On a freshly created Debian sid live system:
```
sudo mmdebstrap --include=linux-image-amd64,live-boot,xserver-xorg-video-
all,phosh --arch amd64 sid debian-live-root http://ftp.pl.debian.org/debian/
sudo chroot debian-live-root passwd
sudo chroot debian-live-root useradd -m -s /bin/bash -p $(openssl passwd -1
123456) user
sudo chroot debian-live-root systemctl enable phosh
cp debian-live-root/vmlinuz .; cp debian-live-root/initrd.img .
sudo mksquashfs debian-live-root root.squashfs -comp lz4
python3 -m http.server -b localhost 8080
qemu-system-x86_64 -machine accel=kvm -m 4G -device virtio-net-pci,netdev=net0
-serial stdio -monitor vc -netdev
user,id=net0,hostfwd=tcp::2222-:22,guestfwd=tcp:10.0.2.252:8080-tcp:localhost:8080,hostname=debian-
live -kernel ./vmlinuz -initrd ./initrd.img -append "console=ttyS0
ip=frommedia boot=live nopersistence
fetch=http://10.0.2.252:8080/root.squashfs"
```
(last command is to start the test VM)
Phosh doesn't start. On the console I see:
```
traps: phoc[362] trap int3 ip:7f684a6d9585 sp:7ffccc2cfe90 error:0 in
libglib-2.0.so.0.6400.4[7f684a69f000+81000]
```
When attempting to start it manually:
```

Starting phosh as root doesn't help:

```
It's also possible that I missed an important step, but I couldn't find
anything related in the doc.
