search on ubuntu

I moved my omeka installation from Mac OS X Server 10.5 to ubuntu Ubuntu 10.04 LTS (lucid) and am having problems with erroneous search results. When I turn on display of errors, it shows

Warning: trim() expects parameter 1 to be string, array given in /var/www/omeka/application/libraries/Omeka/Controller/Action/Helper/SearchItems.php on line 52

I don't see this error when I repeat it on the old server. Thanks for any help.

This post describes an issue that has been fixed in the unstable development version of Omeka.

The fix will be included in the next stable release version.
