On a Lubuntu i386 system in a Lubuntu Desktop session, gnome-network-manager 0.8.9997+git.20110529t170033.9ec4c5d-0ubuntu1 crashed twice with SIGSEGV in gtk_icon_source_set_pixbuf() shortly after logging in. Since the crashes, it seems that attempts to load the applet are happening continuously--a new (blank) icon is constantly added then removed from my lxpanel (at a rate of slightly more than once per second). It looks like the whole lxpanel (not just the notification area) is redrawn each time this happens. In case it's relevant, lxpanel is at version 0.5.6-1ubuntu4.
However, this bug is not specific to LXDE. It also happened to Sam Tygier in a unity-2d session (see bug 797434) on a live CD.
The first bug report was Sam Tygier's bug 797434. Then I reported bug 797494, which was a duplicate. Then I installed some debug symbols, and this bug report has a complete stack trace. Since no significant work has been done in the original bug (bug 797434), I'm marking it (and thus also bug 797494) a duplicate of this bug.

Thanks for your report. Same crash with gnome setting daemon (bug 797575)
Moving to gtk+3.0
