Firejail Dino

Dear fellow Trisquel users,

I tried to firejail Dino on Trisquel 9:
$ firejail dino-im

which returned this:
# Reading profile /etc/firejail/default.profile
# Reading profile /etc/firejail/disable-common.inc
# Reading profile /etc/firejail/disable-passwdmgr.inc
# Reading profile /etc/firejail/disable-programs.inc

# ** Note: you can use --noprofile to disable default.profile **

# Parent pid 6582, child pid 6583
# Child process initialized in 153.61 ms

# ** (dino-im:3): ERROR **: 08:32:39.076: database.vala:29: SQLite error: 14 - unable to open database file

# Parent is shutting down, bye...

Please help. Thank you!
