using pro version 2.4 and qtranslate with 3 languages (german, french and english). Language switching works normally with posts and pages.
When I'm using the Universal Sidebar section, widgets are displayed normally in all languages.
When using Primary Sidebar, Secondary Sidebar, Tertiary Sidebar, Content Sidebar sections, widgets are only displayed in German and English settings, in French setting I only get the default widgets in Primary Sidebar, otherwise nothing. This applies as well to standard widgets like archive, calendar etc. on single instances without widget logic as to language specific widgets using widget logic (i.e. function_exists('qtrans_getLanguage') && qtrans_getLanguage()=="fr" will not show widget, while function_exists('qtrans_getLanguage') && qtrans_getLanguage()=="en" is working normally).
It seems to me that this problem didn't exist before pagelines 2.4.
If I create a custom section following the custom sidebars guide in the wikiand create the new folder in /plugins/pagelines-sections/ and use the code provided in the wiki for sections.php:
the new custom sidebar section works perfectly.
However, I noticed that the part "pagelines_register_sidebar" etc. is not present in the current core pagelines sidebar section.php files which might be a reason for the above mentioned problem wioth most sidebar sections, but doesn't explain why the Universal Sidebar section works normally.
