Using intel’s PowerTOP, I see that there’s a lot of wakeup events from Kopete,
much more than from any other software I have running.  Here’s a paste:

Top causes for wakeups:
  35.5% (158.1)       <interrupt> : extra timer interrupt
  22.6% (100.7)            kopete : schedule_timeout (process_timeout)
   7.3% ( 32.6)       <interrupt> : ehci_hcd:usb2, uhci_hcd:usb3, uhci_hcd:usb5
   7.3% ( 32.6)   USB device  5-1 : USB-PS/2 Optical Mouse (Logitech)
   2.9% ( 12.9)       <interrupt> : ahci, eth1
   2.8% ( 12.3)   <kernel module> : usb_hcd_poll_rh_status (rh_timer_func)
   2.6% ( 11.6)          postgres : schedule_timeout (process_timeout)
   2.3% ( 10.3)             skype : schedule_timeout (process_timeout)
   2.3% ( 10.1)      <kernel IPI> : Rescheduling interrupts
   2.2% ( 10.0)     <kernel core> : ehci_work (ehci_watchdog)
   2.2% (  9.6)             skype : do_nanosleep (hrtimer_wakeup)
   0.9% (  4.2)   USB device  6-1 : MOTORIZR Z8 (Motorola)
   0.9% (  4.1)       <interrupt> : uhci_hcd:usb4, uhci_hcd:usb6, HDA Intel
   0.9% (  3.8)       <interrupt> : PS/2 keyboard/mouse/touchpad
   0.8% (  3.5)       <interrupt> : ata_piix
   0.7% (  2.9)    plasma-desktop : schedule_timeout (process_timeout)
   0.4% (  2.0)            mysqld : schedule_timeout (process_timeout)
   0.4% (  2.0)     <kernel core> : clocksource_register (clocksource_watchdog)
   0.4% (  1.7)                 X : schedule_timeout (process_timeout)
   0.3% (  1.4)           konsole : schedule_timeout (process_timeout)
   0.3% (  1.3)     <kernel core> : wl_add_timer (wl_timer)
   0.2% (  1.1)       <interrupt> : ohci1394, eth0, i915 at pci:0000:00:02.0


I use Jabber, AIM, ICQ and Yahoo in Kopete, if that helps narrowing it down.

I notice also, probably related, that the fan in my laptop barely ever stops
spinning if I have Kopete running, and it’s much likely to happen when it is
not running.

(Yes, I realise 4.2.67 is alpha quality code, just I guess it might be a nice
idea if you kept an eye out for this issue in the future.)
