Description Oldřich Jedlička 2013-06-23 20:53:30 UTC

Application: gwenview (4.10.4)
KDE Platform Version: 4.10.4 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.10.0-drm+ i686
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

I opened gwenview from the Midnight Commander by pressing Enter (Open action) - this automatically openes gwenview on my system. Afterwards the screen showed the picture on right, the list of other pictures in the same folder below and folder tree on the left. The list of other pictures shown that each picture was loading (thumbnails were generated at that moment).

This is a dup of bug 310202, but the bug is closed now. The details of the crash analysis follows:

The core dump contains two threads. One is main() and second one is QInotifyFileSystemWatcherEngine::run.

The important information from the Q_ASSERT shown in all backtraces is that the destructor of QApplication has returned and the instance destruction continued by parent class (QCoreApplication) - the qMetaTypeGuiHelper is NULL (set in ~QApplication() as the last step). The destruction continues to queued events (~QCoreApplicationPrivate destroying postEventList) and there is a GUI event (QMetaCallEvent), which needs the qMetaTypeGuiHelper in its destructor.

The gdb says that QMetaCallEvent's callFunction is Gwenview::ThumbnailCache::qt_static_metacall(QObject*, QMetaObject::Call, int, void**).

The crash can be reproduced sometimes.

Application: gwenview (2.8.5)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-53-generic-pae i686
Distribution: Ubuntu 12.04.3 LTS

-- Information about the crash:
AMD Athlon-64 //1,5 GB-RAM//  I had opened Gwenview in 4 Windows. 2 applications pointed to pictures reside in an Ipad(connected via USB). 2 applications pointed to pictures in an USB-harddisk. There are .jpg and .mov.'s All works fine. As I closed all 4 windows: => CRASH.
Gwenview crashed while closing in several times. 
I hope, this info is useful for you.

Thank you for your commitment.

Comment 2 Nate Graham 2017-09-09 04:44:03 UTC

Is this reproducible with KF5 versions of Gwenview?

> Is this reproducible with KF5 versions of Gwenview?

I cannot verify it, I do not have Linux installed any more.
