            Bug ID: 297032
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: akregator crashes after looking at large graphs.
    Classification: Unclassified
                OS: Linux
          Reporter: haimo.zobernig at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: akregator

Application: akregator (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-17-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
First looked at a post by Louis de Bethencourt (forget which feed, but a very
new one at 
~2:45 pm CEST (GMT+2).  Mar 29, It contained a story about an intersting way of
presenting personal data
by a Nick Felton, including two graphs which appeared rather large when
clickeink on the
[full graph] link. Deleting the tabs corresponding to these 2 graphs took ~
tenish seconds.
Then clicked the Quit button of akregator and the crash happened.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
