Description:
------------
gnupg compiled against gpgme-1.2.0 installs fine but when trying to initialize a new gnupg object, the interpreter segfaults.

The extension compiled with gpgme-1.1.8 works fine.

Thanks for the support.

Reproduce code:
---------------
<?php echo get_class(new gnupg()); ?>

Expected result:
----------------
gnupg

Actual result:
--------------
segmentation fault

After a little research I found that the fix is easy.
gpgme_new() will fail if you don't call gpgme_check_version() before.

See the following patch:

Suggested fix works on issue, with pecl version (1.3.1)

php 5.2.12
libgpgme11 1.2.0

Tip for anyone using pecl and finding this bug report, make the change to the source code in the pear download directory (mine was /tmp/pear/download) and then run pear install gnupg-1.3.1.tgz


PS. Line number is 139

This bug has been fixed in SVN.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.
