I can reproduce this with an empty image in my Recent Documents, on 5.1.0 as well as 5.2.x. I'm almost convinced it happens more consistently when File Explorer is open and not minimized... The same warnings are logged to the console. The warnings about stopping timers only show up preceding a crash. The crash gives either the same backtrace as above, or this one: Qt5Core.dll!QCoreApplication::notifyInternal2+0x73 [C:/Packaging/KritaDepsBuild/ext_qt/s/qtbase/src/corelib/kernel/qcoreapplication.cpp @ 1084] Qt5Core.dll!QEventDispatcherWin32Private::sendTimerEvent+0xcd [C:/Packaging/KritaDepsBuild/ext_qt/s/qtbase/src/corelib/kernel/qeventdispatcher_win.cpp @ 455] Qt5Core.dll!qt_internal_proc+0x288 [C:/Packaging/KritaDepsBuild/ext_qt/s/qtbase/src/corelib/kernel/qeventdispatcher_win.cpp @ 239] USER32.dll!UserCallWinProcCheckWow+0x2f8 USER32.dll!DispatchMessageWorker+0x249 Qt5Core.dll!QEventDispatcherWin32::processEvents+0x7cb [C:/Packaging/KritaDepsBuild/ext_qt/s/qtbase/src/corelib/kernel/qeventdispatcher_win.cpp @ 642] qwindows.dll!QWindowsGuiEventDispatcher::processEvents+0x15 [C:/Packaging/KritaDepsBuild/ext_qt/s/qtbase/src/platformsupport/eventdispatchers/qwindowsguieventdispatcher.cpp @ 74] Qt5Core.dll!QEventLoop::exec+0x1e5 [C:/Packaging/KritaDepsBuild/ext_qt/s/qtbase/src/corelib/kernel/qeventloop.cpp @ 138] Qt5Core.dll!QCoreApplication::exec+0x6d [C:/Packaging/KritaDepsBuild/ext_qt/s/qtbase/src/corelib/kernel/qcoreapplication.cpp @ 1389] krita.dll!krita_main+0x4397 [C:/mykrita/src/krita/main.cc @ 721] The backtracens aren't very informative, though -- though Tiar's shows that the autosave dialog got opened, which is missing in Freya's backtrace. I I'm pretty sure this is the same bug as 459512. I used .psd files to reproduce it originally, and after reverting the commit that fixed that report, I cannot no longer reproduce this one. Okay, let's mark it as a duplicate. *** This bug has been marked as a duplicate of bug 459512 *** |
Created attachment 151739 [details] Crash log for all threads SUMMARY It happens randomly, I don't see anything specific in the crash log. Possibly I caused it myself by 148a5e9bb784d4d84ff5595 (both cases when it happened it was with that changes) but I don't see how it could be relevant... STEPS TO REPRODUCE 1. Start Krita. 2. Possibly press some buttons (I think I was typing at the moment, both times it happened I was doing something) 3. Krita steals the focus and crashes.
