-- Information about the crash:
I copied about 50 files (maybe 150 MB in total) from the local SSD to a NAS. Here ist the relevant line from the "mount" output (username and domain replaced with ******):
//10.0.0.5/Public on /mnt/public type cifs (rw,nosuid,nodev,relatime,vers=1.0,cache=strict,username=******,domain=******,uid=1000,forceuid,gid=1000,forcegid,addr=10.0.0.5,unix,posixpaths,serverino,mapposix,acl,rsize=61440,wsize=65536,actimeo=1)

The crash can be reproduced every time.
