** Description changed:
+ [Impact]
+
+ DokuWiki fails with a 500 internal server error. This is caused by a
+ regression in phpseclib introduced in 1.0.1-3 and subsequently fixed in
+ 1.0.1-4.
+
+ /var/log/apache2/error.log contains entries like the following:
+
+ [Mon Apr 25 16:09:08.998092 2016] [:error] [pid 10897] [client

+ [Test Case]
+
+ 1. Install the following packages:
+ * dokuwiki (0.0.20140929.d-1ubuntu1)
+ * apache2 (2.4.18-2ubuntu3)
+ * libapache2-mod-php7.0 (7.0.4-7ubuntu2)
+ 2. Visit http://localhost/dokuwiki
+
+ [Regression Potential]
+
+ Upgrading to 1.0.1-4 reverts the changes made in 1.0.1-3, making it
+ identical to 1.0.1-2. This version is known to work according to the
+ upstream Debian bug report.
+
+ [Other Info]
+
+ == Regression details ==
+ Discovered in version: 1.0.1-3
+ Last known good version: 1.0.1-2

Facing the same issue as bug #819420 in Debian.

Appears fixed in Debian's version 1.0.1-4, can we get the fix in Ubuntu
Xenial as well?
