unity-window-decorator crashed with signal 7 in g_datalist_id_set_data_full()

[XiuHaotian]

Binary package hint: compiz

ubuntu classic 界面时候经常出现的问题。

我很苦恼。

为什么Ubuntu 11.04那样不稳定？

不过我依然会一直用下去。

It also sounds like a bug similar to the "event_filter_func" crasher, ie https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/748317

The other bug is now fixed and release into Natty. Could you test the new package and report whether the issue still occurs with this new release?

Thanks
