got an error that crashed gnucash. process 8521: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/var/lib/dbus/machine-id": No such file or directory See the manual page for dbus-uuidgen to correct this issue. after i ran dbus-uuidgen --ensure as root, dbus-uuidgen --get successfully returned the id (it failed previously). now gnucash is happy.
