Comment 1 Thomas Lübking 2011-03-23 14:46:12 UTC

see the dupe.
it's not sure if it actually is (you'll have to get a trace using gdb as described over there), but there's no way to ultimately say from this backtrace (and you won't get a better one)

In general, setting the scale method to "smooth" rather than "accurate" would workaround this.
