Occassionally when running vlc by clicking on a video file in Dolphin (about once every 3 days or so), vlc will not open; the mouse pointer will have the vlc icon bouncing for about 30 seconds, and then will revert to the default pointer, but vlc does not open. If I click on a video file again, then the computer freezes. I think if I try to open anything else by clicking on it in KDE, then the computer also freezes, but I'm not 100% positive about that (I've only had limited testing, since I can't reproduce this at will).
This only seems to happen if I have put the computer to sleep (not hibernate, but RAM sleep), but that could just be because I sleep it a few times a day, and this bug hasn't surfaced early enough.
Because the computer crashes, some of the logs do not get saved to disk. But I am usually able to piece a complete log from kernel.log and/or everything.log. I have included a few representative logs below. It seems to involve one core of a quad-core CPU, but not always the same core. Usually it has the message "BUG: unable to handle kernel NULL pointer dereference at (null)" but once with a general protection fault message. The call trace always seems to include __wake_up_common, __wake_up_sync_key, and so on.
I am running up-to-date software as of yesterday, and this has been happing since early August. I'm running linux 3.0.3-1, KDE 4.7.0, vlc 1.1.11. Hardware includes an Asrock z68-pro3, Sandy Bridge i5-2500k not overclocked, 2x4gb DDR3 1600.
Can anyone help me troubleshoot this further, or point me to where I should be filing a bug?

You should see more info about what happens by launching vlc from the command-line instead of from dolphin.

Thanks. I found that it does crash when launching from the command line, but I didn't get a log out of it the last time (it just said "Killed"). However, I think I found the problem, and am currently testing to see if I did.

I think I've confirmed by this point that this is related to a lirc driver, or the interaction with lirc and vlc. So I'm going to change this to solved, even though it isn't technically solved.
