hi,
anybody got an insight into NSS initialisation to tell me if this is a
good fix?
it seems plausible to me, but i haven't tested it, and my OS is so new
it creates the new SQL profiles by default anyway.
anybody got an old system and some time to test if it actually works?
but i'm thinking we need some insight here before backporting the recent
bundled NSS upgrade to release branches :)

Hi,
I would like you to review the following patch:
https://gerrit.libreoffice.org/58756
To pull it, you can do:
git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/56/58756/1
xmlsecurity: nsscrypto_initialize: try to avoid profile migration
https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/NSS_3.35_release_notes
NSS 3.35 and later will automatically migrate migrate profiles from the
old "dbm:" BDB format to the new "sql:" SQLite format.
The new format can be read by NSS 3.12 and later, which is old enough that
it can be assumed to be available.
However LibreOffice still shouldn't migrate the profile on its own:
LO typically uses a Mozilla Firefox or Thunderbird profile, and if it is
a system Firefox with system NSS libraries, then it's probably a bad
idea for LO to migrate the profile under Firefox's nose, particularly
considering the "partial migration" scenario if the profile is
password-protected.
Try to avoid this by checking if the profile is the old format and
explicitly using the "dbm:" prefix to prevent the migration.
