What does this mail_html error mean?

Can I ignore this or is this something important?

Sounds like some sort of missing python module? Did you customize the base system in any way? If you didn't, you can open a ticket on https://jira.ixsystems.com for us to investigate. Please include a debug file (System -> Advanced -> Download Debug)

No. Basically nothing. I just installed ncdu_1.13-1+b1_amd64.deb, but this cant be the reason...
Opened https://jira.ixsystems.com/browse/NAS-114702

Today I received this error, after I got one unreadable sector on my boot SSD this morning. I don't know if that's the reason for these errors. What do you think?
