KSP Version: v0.90.0.0 Beta Linux 64-bit (Ubuntu 14.04.1 LTS) What Happens: Program crashes with core dump when decouplers in a certain condition Mods / Add-Ons: All Stock Steps to replicate: 1) Load craft 2) Launch craft 3) Right click on decoupler and choose decouple. Alt. use staging to decouple. Result: Program crashes with core dump. Notes: TR-2V, TR-2C and TR-18D tested Seems like using some other element below the decoupler can be a workaround.
