Thanks cavemonkey50,

it seems that the original get_bloginfo function (not hooked to init) creates the conflict only with certain parameters.

atom_url
comments_atom_url
comments_rss2_url
description
name
rdf_url
rss2_url
rss_url

Just for info, all parameters related to RSS Feeds generate a different error:

Fatal error: Call to a member function get_feed_permastruct() on a non-object in ...

The strange thing is that the title parameter in the Codex does not exists, so all get_bloginfo('title') calls should be replaced with get_bloginfo('name')

Anyway Dale, one of the WPtouch authors, answered to me that they look into it soon, so until they fix the problem we at least have a patch.

Bye!

Cavemonkey50 you’re right.
This afternoon I made other tests on the conflict between WPTouch and Podcasting plugin, with a clean install of WP 2.3.5. No other plugins installed (no akismet, no hello dolly), default theme, no permalinks set. Only Podcasting and WpTouch.
I tried with latest versions of both plugins and I found where the
problem happens.
Podcasting plugin uses this hook to modify the blog name in the Rss Feed:

add_filter('option_blogname', 'podcasting_blogname_filter');

the function is:

// Change the podcast title
function podcasting_blogname_filter($title) {
       if ( 'podcast' == get_query_var('feed') ) {
       // [cut]
       }
       return $title;
}

when you activate WPTouch, the get_query_var function does not work. In fact, if you comment the hook this way

// add_filter('option_blogname', 'podcasting_blogname_filter');

everything works fine.
I noticed too the non standard use of DB queries, but I didn’t try because I thought that was something related to WPT plugin hooks.
I wrote also an email to the WPTouch author, meanwhile I will try to patch the non standard queries.

Thanks for your reply!

The same error happened to me on a 2.6.3 WP version. It seems there’s a conflict with other plugins. In my case was the Podcasting plugin, 2.0b4 version. My suspect is that there’s a conflict with the WP query made by Podcast to create a podcast feed, but I’ve no elements to confirm this.
I wrote an email on 10/28 to the WPtouch plugin authors to report the bug and they answered “we’ll look into it”.
Today they released a new version, but at the moment I don’t know if this problem was fixed. I will make a test later.
Do you also have installed the Podcast plugin or something similar that creates / modifies WP query?

it’s a strange question 🙂
you can write a plugin with a function hooked up to the publish_post action

function my_custom_field($post_id){
add_post_meta($post_id, 'my_key', 'my_value');
}
add_action('publish_post', 'my_custom_field');

i think that the plugin is not compatible with WP 2.5.x versions
