Did you see this issue right after boot, or only after using
the device for a while?

Hm. I just remembered that I saw an effect like this in some devel
version of ITOS2006 on N770.  The reason was that some process had
used all the file descriptors and therefore Gtk apps couldn't get
shared memory segments with the X server and sapwood server couldn't
load new theme images.

However, Chinook has a large enough amount of file descriptors that you
can have all the pre-installed apps in use and one that has leaked as
many file descriptors as a single process can (thousand) and the device
still works.  So, this might not be the cause.   But to make sure,
please mail what this gives:
	cat /proc/sys/fs/file-nr

OMWeather was earlier leaking very badly (and because it's a Desktop
plugin and Desktop is OOM-protected, the applet could force device to
get very slow and eventually to reboot).

Please attach /proc/meminfo file contents from the situation when
this happens.
