I am able to reproduce this bug on a Natty i386 system. It came up after I updated (via 'sudo apt-get update', 'sudo apt-get upgrade'), rather than immediately after logging in. But I updated very soon after logging in, and I cannot be sure that it had anything to do with this bug.

(I originally reported this as Bug 695243, thinking that my stack trace might be better than the one here. It isn't, so I've marked that as a duplicate of this bug.)

[Eliah Kagan (degeneracypressure)]

Possibly relevant information from my now-duplicate-marked bug report:

"This bug might be related to Bug 685168, which I have been experiencing from time to time lately on this machine (as duplicate bug 692397). When I saw the Apport icon, I had assumed it was that bug again. However, in that bug, the segfault was in g_datalist_id_set_data_full() rather than g_data_set_internal() as is the case here."
