/extra-data/checkout/gnome/gnome-boxes/src/gnome-boxes-search-provider.vala:116 is foreach (var id in ids), and vala indeed generates a g_strdup when doing the iteration. As g_strdup handles NULL string, this probably means we ended up with an invalid string in this list.
I couldn't spot something wrong in there though :( Any chance you can catch this crash in valgrind?

I dont know what that means :( I am new to fedora and new on repporting bugs.
Ok, never mind then, thanks for the bug report and your answer ;) Is it an issue you can reproduce whenever you want, or did it occur only once?
I get it when I do a reboot. It started after latest update where gnome-boxes were updated.
I dosent seem to have any impact on my system, as it is working as usaual.
Just updated gnome-boxes to 220.127.116.11-1.fc18 and no ABRT when rebooting.

+ /* We have to put this in a separate file because vala does not seem to honor "owned"
should be 'separate method'
Did I understand correctly that the issue is that we are calling async methods from the dbus callback, and that vala does not copy the callback arguments in this case, which means they don't stay alive for the whole duration of the async method calls, hence the use of 'owned' to force the copy? If yes, ACK, otherwise I'll have to go back reviewing ;)

Yes, this is exactly the problem, which then gets extra complicated by a valac bug that makes calling methods with "owned" arguments not work in the generated dbus wrapper method.
Pushed to git, will be fixed in next minor release.
