--- Comment #1 from Henri Verbeet hverbeet@gmail.com --- I'm afraid the backtrace isn't very helpful for finding the cause, and I can't reproduce this myself. The address 0x052c3b80 is close enough to libnvidia-tls.so.340.65 that it might somehow be graphics driver related though. The debug messages suggest it crashes either in test_state_block() or at the start of test_color_brush().
