The problem is that Timeshift tries to run notify-send as root and that doesn't work:
time /usr/bin/notify-send "hola" Error al llamar StartSereviceByName para org.freedesktop.Notifications: Se alcanzó el tiempo de expiración
real 1m0,360s user 0m0,005s sys 0m0,011s
As a workaround, setting alias notify-send='/usr/bin/true' in root's .bash_aliases returns expected behavior
