Alexis La Goutte pointed out to me, that when using extcap, the "Capture
Dialog" crashes after selecting a Capture Filter, with BPF compiling enabled.
It does not crash on me on OSX, where BPF compiling is not enabled.
It seems, that pcap_parse crashes in libpcap 0.8 (Ubuntu 14.04 stock install),
if DLT is 147. DLT 1 works fine. I have tested this with the extcap extension,
although I assume, this has nothing to do with extcap in particular.
If the extcap plug-in tells ws, that it's DLT is 147 WS crashes upon selection
of an interface. If the extcap plug-in sends no DLT or DLT 1(EN10MB) WS does
not crash, and the BPF compilation works as it should.
I have filed a bug with pcap
(https://github.com/the-tcpdump-group/libpcap/issues/368), but I am not sure if
it is a bug in pcap, or in the UI, as maybe the UI should prevent calling
pcap_parse if the DLT is not valid or user-defined. The best way to test this
is with extcap (I4f1239b2f1ebd8b2969f73af137915f5be1ce50f)
