https://bugs.kde.org/show_bug.cgi?id=285849

           Summary: digikam crashes when resizing the crop area
           Product: digikam
           Version: 2.1.1
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: Rudolf.Leitgeb at gmx.at

Application: digikam (2.1.1)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

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

1. pick image in digikam, hit F4 for editing
2. draw rectangle within image area for cropping
3. resize crop area by moving its vertical and/or horizontal boundary lines
with the mouse

It is hard to reproduce and (fortunatelyfor me as user) happens only
occasionally, but it's certainly annoying.

The crash can be reproduced some of the time.

-- Backtrace:
