probably happens when the ParseProjectJob is killed in the nested eventloop - ouch. Git commit bcdd01a4abc003fee4d8376a2c1226d8c896ea68 by Milian Wolff. Committed on 04/12/2015 at 17:49. Pushed by mwolff into branch '5.0'. Guard against reentrancy issues that may trigger a crash. When the nested eventloop handles a "stop all jobs" action the job itself may get deleted and subsequently we'd run on a deleted `this` leading to crashes.

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 loading a project that contains a large (huge) body of Tcl files. Since I had no use for the reparsing step that follows the initial import I hit "Stop All" as soon as the project appeared in the Project toolview. This crash ensued. -- Backtrace: Application: KDevelop (kdevelop), signal: Segmentation fault: 11 (lldb) process attach --pid 47367 Process 47367 stopped Executable module set to "/opt/local/bin/kdevelop".
