[digikam] [Bug 366104] New: digikam5 "hangs' @ 100%CPU at exit

https://bugs.kde.org/show_bug.cgi?id=366104

Bug ID: 366104
Summary: digikam5 "hangs' @ 100%CPU at exit
Product: digikam
Version: 5.0.0
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [hidden email]
Reporter: [hidden email]

Application: digikam (5.0.0)
(Compiled from sources)
Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.5.7-ck1-mainline-core2-rjvb x86_64
Distribution: Ubuntu 14.04.4 LTS

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

- opened digiKam5
- connected an iPhone via USB
- used "import & delete selected"
- closed the import window
- checked the new photos in a fullscreen slideshow (manual advance)
- used Browse/Quit or the window close button to exit digiKam5
- `killall -ABRT digikam` after waiting a suitably long enough time and
checking CPU usage

Qt 5.6.1, frameworks 5.24.0 and digikam are installed in /opt/local .

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
