Application: kdevelop (4.7.1)
KDE Platform Version: 4.14.5 (Compiled from sources)
Qt Version: 4.8.6
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages

-- Information about the crash:
- What I was doing when the application crashed:
 I was trying to come up with a "clever" way to coerce KDevelop into importing a qmake-based project (Qt 5.4.1 qtbase). The idea was: let's write a CMakeLists.txt that executes qmake, and see what happens:

cmake_minimum_required(VERSION 2.8.12)

project(qtbase)

find_package(Qt5 5.4 REQUIRED Core)

get_property(qmake_exe TARGET ${Qt5Core_QMAKE_EXECUTABLE} PROPERTY IMPORT_LOCATION)
execute_process(COMMAND ${qmake_exe} qtbase.pro
     WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
)


What happened is this crash.
