1. Please add ctype support to the PHP Requirements in the documentation.
2. Please output a message to the browser that ctype support need to be installed if it is missing.
Novell has ctype support in a separate package.
This applies to SuSE Linux Enterprise Server 10:
http://www.novell.com/products/linuxpackages/server10/i386/php5-ctype.html
http://download.novell.com/Download?buildid=fq1bbSYtUgk~
and to OpenSUSE 10.2, 10.3, 11.0 and 11.1:
http://download.opensuse.org/repositories/server:/php/
When package php5-ctype is not installed phpMyAdmin stops with that message in Apache's error_log:
Call to undefined function ctype_space() in ... libraries/sqlparser.lib.php on line 286
However, nothing about that error is shown in the browser.
Fixed in subversion, thanks for reporting.
