I did. The results are below.
Remark that I have to plug twice the device before getting something

may also be because when inserting the device, the udev machinery tries
to use some exec that segfaults (same as ideviceinfo).

Do you need "set solib-search-path" or "set sysroot"?

The same device on a wheezy platform works fine, btw.
