Redmine

Since we moved to 3.2.3 we can not delete any version anymore using any account (including Admin ones).
Even if the versions:

• Don't have any "issue for this version"
• Are not shared at all
• Are in any status (closed, lock...)

Each time we try to delete a version, the message "Unable to delete version." is displayed and the version is not deleted.

Here are our versions in detail:

  Redmine version                3.2.3.stable
  Ruby version                   2.2.5-p319 (2016-04-26) [x86_64-linux]
  Rails version                  4.2.5.2
  Environment                    production
  Database adapter               PostgreSQL
SCM:
  Subversion                     1.6.11
  Git                            2.8.4
  Filesystem                     
Redmine plugins:
  no plugin installed

If this is a 3.2.3 defect I guess we would not be the only ones facing it. But well, maybe, a first one has to raise issues?
