Sentry Crash Report:
Attachments: New crash information added by DrKonqi

Description Avihay 2010-12-17 14:03:34 UTC 
Application: lancelot (1.9.5)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-26-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I accidentally filled the hard disk.
Then Lancelot showed me 4 MessageBox's about unable to open file corresponding to 4 main categories in the menu: apps, computer, contacts, documents.
Then instead of terminating gracefully, it fell on __GI_clock_gettime.
Most of my crashes are related to some sort of issue with gettime

-- Backtrace:
Application: Lancelot (lancelot), signal: Segmentation fault

New crash information added by DrKonqi

lancelot (1.9.5) on KDE Platform 4.5.3 (KDE 4.5.3) using Qt 4.7.0

- What I was doing when the application crashed:
I tried to open Lancelot again before freeing more disk space, and this is the newer backtrace.
