can't work in Ubuntu wireshark

[liyihuanx]

get the error message:

Lua: on packet 19377 Error during execution of Listener packet callback:
/usr/share/wireshark/rtp_h264_extractor.lua:76: attempt to index upvalue 'fp' (a nil value)

[volvet]

The extractor try to dump files in default directory. Seems it is unwritable, try to modify the code like this:

local fp = assert(io.open(os.getenv("HOME").."/dump.264", "wb"))
