LIBFETION VERSION: 1.0
OS: Linux

OTHERS:

应该是文件读取权限问题，
但不应该导致程序崩溃...

难说，有可能是引用了跟文件有关的操作，然后访问了非法��
�针挂掉。例如
File *file = fopen(/*not exited file*/)
file->ops

今天开电脑后,发现这个问题居然重启之后就好了,奇怪了!
 昨天打印的信息能看出来什么头绪么?

do nothing for this.

I try to reproduce this case such as read NULL icon from system.
But the app didn't crash...
So I think we can set invalid flag for this issue.

没找到提bug的地方，直接发邮件了，希望能收到。

环境： 
gentoo
kde 4.3
qt 4.5.3 
gcc 4.4.1
linux-fetion 1.1

应该和kde没有关系吧，gdb 
的时候显示一些和kde库相关的东西, 有什么冲突吗。
你看看，谢谢。
