Wireshark-dev: Re: [Wireshark-dev] tshark-1.0.2 (dumpcap) signal abort core saved, see the stac

Hi,
 
Thanks, for the information.
 
What I see on looking at stack trace, for some reason, tshark is calling signal-handler twice.
Once, with frame #5 and once with  frame #14.
I had created a bug #2767, along with a fix that avoids the second call to signal-handler.
If someone can take a look on that. Fix has been kept in state to-review?
 
Thanks,
Moheed

Hi,

 From the looks of it glib runs into trouble, but not obvious why. I think you
should file a complete bugreport at https://bugs.wireshark.org. Be sure to fill
out all info requested.

Thanx,
Jaap
