So, it happened only once and never again? Or you didn't even try? And the spam-report plugin works most of the time? Please give a little bit more background.

The backtrace ends somewhere related to using the "Spam" button on the toolbar:

| #1  0x082148bb in activate_learn_button (toolbar=0x92ddc10, type=LEARN_HAM,
| style=<value optimized out>) at toolbar.c:933
| No locals.
| #2  0x082131b5 in toolbar_learn_cb (widget=0xa22c2d8 [GtkMenuToolButton],
| data=0xa318770) at toolbar.c:1233
|        toolbar_item = 0xa318770
|        mainwin = <value optimized out>
|        msgview = <value optimized out>

src/toolbar.c:

    930                 gtk_widget_show(toolbar->learn_spam_icon);
    931         } else {
    932                 gtk_tool_button_set_icon_widget(
->  933                         GTK_TOOL_BUTTON(toolbar->learn_spam_btn),
    934                         toolbar->learn_ham_icon);
    935                 gtk_tool_button_set_label(
    936                         GTK_TOOL_BUTTON(toolbar->learn_spam_btn),
    937                         _("Ham"));
    938 #ifndef GENERIC_UMPC

This is where it toggles the bogofilter "Learn as Ham/Spam" button between "Ham" and "Spam" and vice versa depending on the message that is selected.

Line 933 is where it crashed inside glib2 (gtype.c), because the button pointer passed to it wasn't anything sane it could work with. Most likely it pointed to corrupted data structures which glib2 could not handle gracefully.
