在LEAN源码中编译，界面打开出错

[dwj0]

你好， 我用 788c5c4 这个提交的版本编译的固件，在网页中打不开界面，提示如下:
/usr/lib/lua/luci/dispatcher.lua:469: Failed to execute cbi dispatcher target for entry '/admin/network/appfilter'.
The called action terminated with an exception:
/usr/lib/lua/luci/util.lua:200: attempt to get length of local 'str' (a nil value)
stack traceback:
[C]: in function 'assert'
/usr/lib/lua/luci/dispatcher.lua:469: in function 'dispatch'
/usr/lib/lua/luci/dispatcher.lua:121: in function </usr/lib/lua/luci/dispatcher.lua:120>

请教解决方法

我把版本回退到上一个，可以正常打开
