nautilus crashed with SIGSEGV in mount_cb()

After updating and upgrading the system (18.04 without proposed updates enabled), I opened up some programs to check how they react. nautilus, gnome-tweak-tool, gnome-software, firefox, thunderbird, gnome-control-center,gnome-disk-utility... In nautilus I decided to mount all my hard drives. (8 partitions). After mounting the third and trying to mount the fourth nautilus crashed, while in the background the other programs were opened or were still loading...
