[issue] crash with busy projects when I add a group track


I’m experiencing a lot of crashes with C8.05 with bug busy projects mainly when I add a group track.
I’ve attached some dmp files http://www.wetransfer.com/downloads/01adb05a25751d8ebbe68315f758c37620150308122026/edccef78f627c0d1ac06368365995a1a20150308122026/12a5a5 here.
I’ve no idea why it happens but it’s extremely annoying because my system is not stable.
Please help me!!
