[power]: gnome-settings-daemon crashed with SIGSEGV in magazine_chain_pop_head()

[Jeremy Melanson]

About an hour after logging in, gnome-settings-daemon crashes. Other than files that are thumbnailed, all of my GTK/Gnome icons revert to a "plain sheet" icon. This can be reproduced by logging off/on, and waiting for about an hour.

[Jeremy Melanson (jmelanson)]

Captured debug output from gnome-settings-daemon at the point where my icons go haywire, and whoopsie reports that a problem occurred.

I renamed the gnome-settings-daemon binary to gnome-settings-daemon.bin, then put a shell script wrapper around it. Hence the reason that the log reports gnome-settings-daemon.bin. As such, that can be ignored.

At one point, it appeared that I was able to get my icons back by killing gnome-settings-daemon. They would appear normal when it restarted. This does not currently seem to be the case.
My GTK style and fonts are ok, however.
