[pkg-php-pear] Bug#822771: php-pear: Invalid argument supplied for foreach() in /usr/share/php/PEAR/Command.php on + XML Extension not found

[Ivan Sergio Borgonovo]

Package: php-pear
Version: 1:1.10.1+submodules+notgz-8
Severity: grave
Justification: renders package unusable

I discovered I've the same problem described here:
http://serverfault.com/questions/589877/pecl-command-produces-long-list-of-errors
examining horde log files

A long list of
Invalid argument supplied for foreach() in /usr/share/pear/PEAR/...
ending with

PHP Warning:  require_once(/lib/Application.php): failed to open stream:
No such file or directory in /usr/bin/horde-alarms on line 21
PHP Fatal error:  require_once(): Failed opening required
'/lib/Application.php' (include_path='.:/usr/share/php:') in
/usr/bin/horde-alarms on line 21

This also seems to be related with some pear issue not setting horde_dir

Simply running
pear list-all
or any other pear command end up in the same list of
Invalid argument supplied for foreach() in /usr/share/pear/PEAR/...
ending with
XML Extension not found

thanks
