Manuel, my guess is that it is a problem of the HTTP MTP add-on.
Unfortunatelly, that add-on has quite a number of bugs and I really invite users to use IIOP instead, even because, under most circumstances, IIOP performs much better than HTTP!
The good news is that Joan Ametller is looking after HTTP MTP and he will soon distribute a new version of it.
