Description jat255 2016-02-09 19:23:53 UTC
Application: digikam (5.0.0-beta4)

Qt Version: 5.5.1
Operating System: Linux 4.4.1-2-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
1) Tagged a face using Ctrl+click method
2) Typed in the name and pressed "Enter"
3) Segfault occurs right after pressing "Enter"

This does occur every single time, but it usually happens after tagging a couple of photos. It seems as though the tag is saved successfully, as the next time I load Digikam, the correct tag is there. I can continue tagging a few more photos, and then it will crash. This happens on different photos, and with different tags.

- Custom settings of the application:
Using digikam-git and kipi-plugins-git Arch packages from AUR with OpenCV 3.0.0 (self-compiled with contrib modules)

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

It crash in Qt. 

Which Qt version you use ? Which digiKam version you use ? 

Look in Help/Components Info dialog for details.

Some additional info: This collection is on a network shared drive mounted with CIFS. I can tag reliably without a crash if I only use the mouse to switch from photo to photo. The crash seems to happen more frequently if I am tagging and then use either the "Space" shortcut or the Left/Right arrows to switch to the next photo.

Comment 3 jat255 2016-02-09 21:17:12 UTC
After some more testing, it looks like the crash comes if I change away from the image before the face tag has a full chance to save to disk. Since I'm over a network and some of my RAW files are on the larger size (16MB), it can take a second or two for the tag to save. If I wait until the tag sort of flashes (which I assume is when the image is saved and reloaded), I don't run into any crashing problems. Trying to switch away from the image before this happens seems to be a surefire way to cause the segfault.
