Bug report: svn assert failure: svn: subversion/libsvn_client/merge.c:3128: merge_dir_deleted: Assertion `delb != ((void *)0)' failed.

Hi all,
I am asking for confirmation before reporting a bug

Using Subversion 1.8.8 installed from Ubuntu 14.04 packages, svn
crashed while performing a merge operation involving a replaced
directory.

I already reportted this bug to Ubuntu Launchpad as
https://bugs.launchpad.net/ubuntu/+source/subversion/+bug/1288829

I was able to reproduce the bug with Subversion 1.9.0-dev trunk
(r1577730) with a self-contained test case (see attachment).

Can I report this to the Issue Tracker?

Regards,
Danilo Piazzalunga
