Comment 20 for bug 701765

Uhm. The open_basedir has /var/lib/php which is a valid prefix for /var/lib/phpmyadmin/, and it has always (for two years until wednesday when this bug appeared) worked with this open_basedir string.

To further clarify:

[...]:/usr/share/phpmyadmin/:/var/lib/phpmyadmin/:[...] works
[...]:/usr/share/phpmyadmin:/var/lib/phpmyadmin:[...] works
[...]:/usr/share/php:/var/lib/php:[...] does not work

which seems to mean that it is now treating paths without a trailing slash as directory names instead of prefixes, which is what the specification says.
