Is this still problem on edgy?

I can't say, I'm afraid

I tried upgrading to edgy but it screwed up the wireless connection on my laptop so I'm not going to edgy on my main machine until this is fixed.

Thanks for your report, and sorry for the long delay. I recently rewrote all this code upstream in terms of libpipeline and I believe it no longer suffers from the memory handling bugs that led to this segfault; the rewrite will be in man-db 2.6.0.

This bug was fixed in the package man-db - 2.6.0.2-1

---------------
man-db (2.6.0.2-1) unstable; urgency=low

  * New upstream release:
    - Fix a segfault when scanning links to empty pages (closes: #622104).
    - Once we've seen at least one record in a page's NAME section, ignore
      any further records that don't include a whatis description, as they
      tend to be noise.
  * Remove unnecessary .la files (closes: #622443).

man-db (2.6.0.1-1) unstable; urgency=low

  * New upstream release, fixing test failures in 2.6.0 (closes: #621867):
    - Ensure that the target of a symlink or .so chain is always recorded as
      a real page.
    - Read a user-specified configuration file even if HOME is unset.

man-db (2.6.0-1) unstable; urgency=low

  * New upstream release:
    - Search the full manpath when expanding .so directives in manual pages.
      As part of this, '.so name.1' should now work as well as '.so
      man1/name.1' (closes: #503472, LP: #411534).
    - Handle roff named glyphs and perldoc strings in NAME sections (closes:
      #601025).
    - Don't start a pager if stdout is not a tty.
    - Allow passing multiple sections to whatis and apropos (closes:
      #571285).
    - Provide byte positions in manconv errors (closes: #562789).
    - Make mandb error output neater when stderr is not a tty.
    - Fix failure to display manual pages in some encodings when installed
      setuid.
    - Don't ignore SIGPIPE while forking iconv (closes: #597756).
    - Remove obsolete subdirectories of cat directories (closes: #558804).
    - If mandb sees that A is a symlink to B, it should never store a whatis
      reference for B (closes: #204249).
    - Print commas in roman rather than bold (thanks, David Prévot; closes:
      #600002).
    - Consider .PD requests as paragraph breaks (closes: #611012).
    - Reset SIGPIPE to SIG_DFL on startup, to avoid noisy output in the
      event that mandb was started from a context where SIGPIPE was ignored.
    - SECTION entries in a user configuration file now override those in the
      system configuration file, rather than appending to them.
    - If the user asked for an explicit section, sort exact matches first.
    - Rewrite all remaining subprocess handling in terms of libpipeline,
      especially some crash-prone code in catman (LP: #27738).
    - The default less prompt now includes "(press h for help or q to quit)"
      to help novices find their way around
      (http://brainstorm.ubuntu.com/idea/25975).
    - Fix a segfault when 'man -K' tries to display certain pages.
    - Fix a segfault in some situations when processes are killed by SIGHUP,
      SIGINT, or SIGTERM (LP: #218336).
  * Avoid unnecessary metadata writes to /var/cache/man when doing recursive
    chown (thanks, Iustin Pop; closes: #619726).
