The tool->canvas is only set on tool_palette.c on_tool_select() at line 400:
    canvas_set_tool(canvas_lookup(GTK_WIDGET(tb->widget)), tb->tool);
Which means the users have to click the text-tool button at least once to set the tool->canvas to avoid the crash.

Please report the bug to upstream. Thanks.
