Title:
  man-db segmentation fault after processing trigger

Status in man-db:
  Unknown
Status in man-db package in Ubuntu:
  Confirmed

Bug description:
  Almost every time I tried to install a package which processes trigger
  for man-db at the end of the setting up phase using apt, I get the
  segfault. The message "Segmentation fault (Core dumped)" appears.

  I expected mandb to finish repopulating the mandb database so all the
  manual pages can be accessed via the "man" command. Instead, I got
  segmentation faults whenever it tries to populate mandb database.

  It seems that there are invalid characters passed somewhere, but it
  shouldn't cause segmentation faults like this.

  Here's an example of man-db segfaulting whenever I try to install a
  package: https://paste.ubuntu.com/p/wXsnfWvs8t/

  Here's the output of dmesg: https://termbin.com/wtfd

  Here's the output of mandb --debug:
