Hi,

I come accross a problem in which some time wireshark crash and i can
see "segmentation fault" on console.

i have created dissector in which i guess problem with tree struct and
ett variables, i think i have not properly define.

I read that *The expansion of this node is controlled by the |ett_foo|
variable.*

for example i click on packet frame which have long tree and than i move
directly to packet frame which has smaller tree. so i guess wireshark
remember that last time i have open 5th element of tree but this time
packet frame do not have 5 element so it crash.
What's the backtrace when it crashes? It seems quite unlikely that this element expansion issue is the real cause.
