Hi,

This top of stack seems to be the end of g_message delivery of a backgrounded process to TTY. Before that it's a GLIB assert on something pango is processing, but it's unclear what. Maybe the rest of the backtrace would show, but it's not there.
Wild guess? pango / cairo libs are not up to date?

Thanx,
Jaap

I have just built the latest stable version of wireshark on Slackware 12.2, after building all of the prerequisites.

Try running the GNU Debugger (gdb) and launch Wireshark from it and show us the back trace so we can get an idea of what is going on. It's pretty simple:

gdb wireshark
 <snip>
(gdb) run
 <receive segmentation fault message>
(gdb) bt 10

 [ snip ]

Please note the transcribed octal in stack frame #3.  The 8-bit characters
kept driving emacs nuts when I c&p'd from the window in which I was running
wireshark, so I had to paste them into an emacs on that window and
transcribe.  It's <capital O-acute>\205<capital U-umlaut><mu>iy<capital
U-umlaut><mu>Es<capital O-circumflex><mu>\024 on my screen, in case that's
actually important to know.

I posted the requested gdb traceback a week and a half ago.  Does no one have
anything to say about it?  I'll remind you that I am not a C programmer, and
need a lot of help interpreting the results so that I can get on with the
actual work that this is holding up.
