Hi,
I experienced a crash with the new filtering features added in 0-8-15.
I updated to the nighlty build 2001-02-21 and still have the same problem.
I use RedHat 7.0, but ethereal has been complied with egcs-2.91.66
(and not with that tricky gcc-2.96 used by RH7.0). Here's what ethereal
-version tells us:
ethereal 0.8.14, with GTK+ 1.2.8, with libpcap 0.4, with libz 1.1.3,
without SNMP
The way to reproduce the bug is quite tricky, so I'm afraid this message
is gonna be a bit long. Sorry for that...
I select a packet I want to filter out, then right click to get Display
Filters. Click on Add _expression_. Then I get some GTK errors...
Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkObject'
Gtk-CRITICAL **: file gtksignal.c: line 724 (gtk_signal_connect):
assertion `object != NULL' failed.
Simply clicking Accept at that moment, generates some more GTK errors:
Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkObject'
Gtk-CRITICAL **: file gtksignal.c: line 724 (gtk_signal_connect):
assertion `object != NULL' failed.
Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkEditable'
Gtk-CRITICAL **: file gtkeditable.c: line 557 (gtk_editable_get_position):
assertion `editable != NULL' failed.
Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkEditable'
Gtk-CRITICAL **: file gtkeditable.c: line 488 (gtk_editable_get_chars):
assertion `editable != NULL' failed.
...and a seg fault core dump. Here's the stack trace cooked with gdb:
Program received signal SIGSEGV, Segmentation fault.

Finally, this bug doesn't happen when I click Filter (bottom left)
and then Display Filters... Is this only a GTK problem ???
Thanks for the quality of ethereal (never had any problems before ;),
Regards,
Theo
