Title:
  gimp freezes, crashes on "open", "save as", "print"

Status in gimp package in Ubuntu:
  Invalid

Bug description:
  gimp freezes, using 80% CPU, when a user attempts Open, Save As, or
  Print.  Must kill process.

  gimp 2.2.2-1ubuntu
  libgnomevfs2-0  2.10.0-0ubuntu55
  libgtk2.0-0     2.6.4-0ubuntu5
  libgnomeui-0    2.10.0-0ubuntu1
  Ubuntu (hoary)

  I know this is reported in several similar bugs, but here's some
  additional info.  On our systems, this behavior happens for ldap user
  accounts (libnss-ldap, libpam-ldap).  It _does_not_ happen for local
  accounts in /etc/passwd.

  Workaround
  If the ldap user has a local account entry in /etc/passwd, this bug disappears and gimp works fine.  The user does not need entries in /etc/shadow or /etc/group.

  nsswitch.conf specifies files first:
  passwd:         files ldap
  group:          files ldap
  shadow:         files ldap
