Hi Josh, Sorry not to have complied with the posting guidelines, previously. OS - Ubuntu 9.10 Karmic on x86 Kernel - 2.6.31-22-generic ros-cturtle-visualization: 1.2.0-30 - debian installation I use a scan_to_scan_filter_chain from laser_filters along with the raw laser scan from hokuyo_node. It crashes automatically, just randomly. Here is the backtrace.
