-- Information about the crash:
- What I was doing when the application crashed:

kdevelop had opened a code window with information about class method. On a click outside the window kdevelop crashed. I suspect, however, some kind of memory problem. On a VM with 1GiB of main memory and 1GiB of swap top showed after the crash:
