Frequently, I like to copy the output I am getting in the DebuggerOutput Window (View->Debug Windows->Debug Output). Sometimes I can right mouse click and use the copy output to clipboard and it works. Most of the time it doesn't work, so I try Cntrl-A to SelectAll, then either Cntrl-Insert or Cntrl-C to copy. In nearly every case, Lazarus crashes.
I am using Kubuntu 15.10 64bit.
