Wireshark · Ethereal-dev: [Ethereal-dev] curious behaviour in 13956

[Herbert Lischka <herbert@xxxxxxxxxxxxxxxxx>]

Hi list,

first of all, thank's for the fast fix in 13955

now I have a little strange behaviour in 13956:
I have a large file with 26857 TCP, IPX and UDP packages.
I want to filter only UDP packages and after 19028 packages this 
segfault occurs:

can anybody help me, or can I help somehow ?

best regards
H.Lischka
