Git commit a20ceb23493324c09d95e3a0440e8d6dca93a31f by Marco Martin. Committed on 23/10/2014 at 12:25. Pushed by mart into branch 'Plasma/5.1'. crash--, create the corona on heap creating the corona on the stack makes the app crash on close, because the corona tries to delete itself when the window closes. this also meand this code will *not* leak M +3 -1 shell/main.cpp M +5 -0 shell/standaloneappcorona.cpp M +2 -0 shell/standaloneappcorona.h http://commits.kde.org/plasma-workspace/a20ceb23493324c09d95e3a0440e8d6dca93a31f
