Still duplicates when batch-adding files

[Ludo]

This post just to let devs know that upgrading to v. 1.4.25 didn't fix the "duplicates when batch-adding" issue for me, despite it should have been - according to dev team announce - by v. 1.4.24.
I'm facing this bug approximately since I've upgraded to 1.4.22 or .23, and the only file that gets duplicated in the database is always the last in the batch-add summary page.
Before posting test account etc., I would like to know if it's still a known issue or it really and definitely got fixed by v 1.4.24.
Thanks in advance.
