Comment 86 for bug 36581

well you would need the debuginfo for the gdb trace.
g_pattern_match is called indirectly from poll_file() or
node_add_subscription() or node_remove_subscription()
Since your log seems to indicate it is looping on
node_remove_subscription. This again seems to indicate an
error looping on a corrupted node list that time a children
list within a directory...
