Closing and reopening the notebook via the doesn't generate the error.

I started getting similar looking traces (see below) after upgrading from 0.54 to 0.56.
However, as far as I can see, everything works alright.
The messages are not only when lauching zim, but whenever I switch pages.
Furthermore, in my case thes errror messages only occur,
when zim is running on a different machine than the X server.

Same here running the ZIM package from the PPA on Ubuntu 12.04. The crash report pops up in Unity and in XFCE4.
