It's true, Oneiric beta 1 has the bug. It's strange as at some point (don't remember exactly when in the last week or this week) this bug were repaired, but the next dist-upgrade brought the bugs back.

D (tenswiths) wrote :

I'm using Oneiric Beta 1, and just had this bug occur. There are no obvious symptoms I can see, other than apport reporting it. Some updates for Compiz have just been released, I think, which may be causing the problem. The crash occurs around 5-10 seconds after opening ccsm, even without doing anything. I have been able to do this 4 times in a row.

As I say, even though the crash is reported, the window remains open, and seems to be running as normal (I can still change options, for example).

Jason Warner (jasoncwarner) wrote :

I got this when I tried to to change the reveal mode setting in the Unity plugin. I got it to happen each time I used that.

To be precise, I did:

* unity --reset
* I like to have both the top left and bottom left corners as reveals for launcher
* opened ccsm
* changed reveal to left and top-left. (crash)
* changed reveal to left, top-left and bottom-left (crash).

I did a fresh install of Oneiric Beta 1, updated everything, and installed ccsm. When I tried to do anything, ccsm crashed and wouldn't let me change any settings.

Adding my user account to the video group allowed the settings to take affect (I needed to do this to get glx running). I am now able to get smaller icons and can get the opacity to change. However, when I choose the experimental tab I still get a dialog that ccsm crashed unexpectedly- but there's no other problems. The crash dialog is only shown once (and apport isn't run).

Fairly certain it's not a driver problem - it's not related to it.

Same as #29. I don't actually have to do anything to get the bug, it just appears but the window continues to work.
