Looks like this could enough for the developers: it seems that the crash comes from a call to g_realloc_n() at debug-sender.c:207. What other information do you expect? Of course, the crash could come from memory corruption elsewhere, and which is only unveiled while constructing this GObject, but, well, another trace won't help AFAICS.
