Reading gdb backtraces from Gtk+ applications can be a pain, as the signal emissions tend make them very long and hard to read. Today i wrote a small application that compresses signal emissions and some other common gnome stuff in gdb backtraces.

For example, take this 147 frames long backtrace i’m currently working on. Its pretty much a pain to read.

With my app it turns into this instead, which is much nicer. Here are some examples:

#7 ... segfault caught by bug-buddy
#8 <signal handler called> ()
#9 __kernel_vsyscall ()

#36 gtk_scrolled_window_destroy (object=0x82bc538) at gtkscrolledwindow.c:799
     ...
#43 gtk_object_dispose (gobject=0x82bc538) at gtkobject.c:418
#44 gtk_widget_dispose (object=0x82bc538) at gtkwidget.c:7851
#45 fm_tree_view_dispose (object=0x82bc538) at fm-tree-view.c:1457

#115 gtk_object_destroy (object=0x82d0200) at gtkobject.c:403
#120 ... emitting signal 219 on instance 0x5954
#121 _gtk_action_emit_activate (action=0x82c8e60) at gtkaction.c:872

#130 gtk_window_key_press_event (widget=0x82d0200, event=0x83716e8) at gtkwindow.c:4961
#140 ... dispatching GdkEvent 0x83716e8 to widget 0x82d0200
#141 g_main_context_dispatch (context=0x819fca0) at gmain.c:2064

Any chance something like this could be integrated with bugzilla?
