The same problem here. For all themes and files on standard Linux webhosting I got
Warning: file_get_contents(/<my-wp>/wp-content/<my-wp>/themes/<theme>/<file>.php) [function.file-get-contents]: failed to open stream: No such file or directory in /<my-wp>/wp-content/plugins/codestyling-localization/codestyling-localization.php on line 489
where <my-wp> is absolute path to directory with wp installtion.
On my local AMAHI server [see amahi.org – based on Fedora 12] where the directories structure is not standard I had no warning but no functionality too.
BTW: Plugin generates good .mo/.po files – I moved .mo file from my theme to one of plugins folder try to edit it and move back and it works.
