[Bug 234307] New: segfault trying to delete an image

https://bugs.kde.org/show_bug.cgi?id=234307

Summary: segfault trying to delete an image
Product: digikam
Version: unspecified
Platform: Unlisted Binaries
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: [hidden email]
ReportedBy: [hidden email]

Application that crashed: digikam
Version of the application: 1.1.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-02063104-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
i was in the image preview, where there's a row of images across the top and
the current image is displayed in the bottom. tag info was open in the right
sidebar, and albums view was open in the left sidebar. i had just pushed
spacebar to get to the next image, and then i pushed delete to delete that
image. this caused a segfault.

-- Backtrace:

[Bug 234307] segfault trying to delete an image

Igor,

please install digikam-debug package to get a full backtrace and post there a
new trace.

Alos, use digiKam 1.2.0, the last stable version. Perhaps it fix your problem.

Andi,

if crash comme from digiKam, sound like a missing QPointer protection for a
dialog, somewhere. Right ?
