Ajax error when clicking save on cancel with panels IPE

Hello,

I use Panels IPE to customize some pages. All works good, I can popup panels ipe, change my content etc.... but when I click save or cancel button on the bottom of the page, I go to a blank page with ajax errors.

Here is the kind of errors I get

[{"command":"settings","settings":{"basePath":"\/drupal\/","pathPrefix":"en\/","ajaxPageState":{"theme":"mytheme","theme_token":"JX5LHE1CabYYxB8uuSMAoMhtQP0FeY8zeoxftuE5PoY"},"overlay":{"paths":{"admin":"node\/*\/edit\nnode\/*\/delete\nnode\/*\/revisions\nnode\/*\/revisions\/*\/revert\nnode\/*\/revisions\/*\/delete\nnode\/add\nnode\/add\/*\noverlay\/dismiss-message\nadmin\nadmin\/*\nbatch\nnode\/*\/translate\nuser\/*\/cancel\nuser\/*\/edit\nuser\/*\/edit\/*\nnode\/*\/display\nuser\/*\/display\ntaxonomy\/term\/*\/display\ndevel\/*\nnode\/*\/devel\nnode\/*\/devel\/*\ncomment\/*\/devel\ncomment\/*\/devel\/*\nuser\/*\/devel\nuser\/*\/devel\/*\ntaxonomy\/term\/*\/devel\ntaxonomy\/term\/*\/devel\/*","non_admin":"admin\/structure\/block\/demo\/*\nadmin\/reports\/status\/php"},"pathPrefixes":["en","fr"],"ajaxCallback":"overlay-ajax"}},"merge":true},{"command":"endIPE","key":"panel-context-page-home-page-home-panel-context"}]

I use the latest jquery update with jquery 1.10; but I also tried 1.7, 1.8, 1.9 with the same results, I cannot go under 1.7 because I have some plugins that need, at least, jquery 1.7.

I tried to look at the issue queue for the same kind of problem but the only issue I found is old and related to panels 6.x, so I create a new one for 7.x.
