我的FC3的KDE任务栏突然不见了。怎么回事啊？

frank9090

我的系统是FC3,内核是2.6.12,今天出去办事回来后突然发现任务栏不见了。reboot后显示错误如下所示：
[frank@fc3 ~]$ kicker
[frank@fc3 ~]$ terminate called after throwing an instance of 'std::bad_alloc'
what(): St9bad_alloc
kicker: crashHandler called
KCrash: Application 'kicker' crashing...
[frank@fc3 ~]$ sending IMStart with 0 chars to 0x8748d48
sending IMEnd with 0 chars to 0x8748d48, text=
terminate called after throwing an instance of 'std::bad_alloc'
what(): St9bad_alloc

重新执行#kicker问题依旧。
请教大家怎么解决啊？
