-- Information about the crash:
In the debugger view, an dock with an assembler window was open. When I switched to the debugger view (indirectly with Run/Debug), I got a Dialogbox talking about a command sent to the debugger while it was not running (presumably from the already open Assembler window). After dismissing it, kdevelop crashed.

 -- Backtrace:
