Summary: digiKam crashed when generating panorama pic
Product: [Applications] digikam Reporter: Axel Krebs <axel.krebs>
Component: Plugin-Generic-PanoramaAssignee: Digikam Developers <digikam-bugs-null>
Status: RESOLVED FIXED    
Severity: crash CC: caulier.gilles
Priority: NOR Keywords: drkonqi
Version First Reported In: 4.8.0

Sentry Crash Report:

Description Axel Krebs 2015-03-22 18:02:55 UTC 
Application: digikam (4.8.0)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-31-generic x86_64
Distribution: Ubuntu 14.10

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

DG crasher when generating a panorama pic containing only 3(!) original pics, size about 30 MioPixels each.
Space in HD is limited (~97% full of 2 TB), but could run out of memory when procesing pics.

SUGGESTION: make a worst-case-scenario calculation fro potentiall needed space requirements, _before_ starting panorama generating.


Axel

The crash can be reproduced sometimes.

-- Backtrace:
Application: digiKam (digikam), signal: Bus error
