--- Comment #7 from Piotr Mierzwinski <piotr.mierzwin...@gmail.com> --- OK. Sorry for not clear report. I didn't get a crash in result my activities only main window of KDevelop disappears. Crash happens later. Main windows of KDevelop disappears, but I can see working process in list of processes. I'm not able to restore it (main window). I kill it and I get crash, what is result of killing I suppose. I can reproduce it every time. My steps are following: 1. To dependencies I add some subdirectory (main->sub1->sub2->sub3) of my project ("Launch configuration", Action: Build) 2. I modify any file from this directory 3. I invoke "Run -> Execute Launch" (with selected top directory of project). In this moment main window of KDevelop may disappears, if not I can see message like below. This is output from Build view: /run/media/piotra/FreeAgent/piotr/Projekty/Qt/qtcmd_work/qtcmd_git/qtcmd2/build> make -j8 zipsubsystem.o *** Killed process *** Seems like KDevelop think that something is running, because both tool buttons related with stopping running jobs are enabled. In first "Menu allowing to stop individual jobs" I can see: "my_project_name, changed_file_name: build" 4. Again I invoke "Run -> Execute Launch" In this moment main window of KDevelop disappears. When I select as target binary file (I mean entry with the same icon like already put by default executable file) also main window of KDevelop disappears. When I run it from konsole I can see such output in last lines: Launch Configuration: "qtcmd2" "No environment group specified, looks like a broken configuration, please check run configuration 'qtcmd2'. Using default environment group."
