            Bug ID: 338666
           Summary: Kalzium crashes when selecting >File >Export Data...
           Product: kalzium
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kalzium at kde.org
          Reporter: walch.martin at web.de

Application: kalzium (2.4.02)
KDE Platform Version: 4.14.0 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.15.10-gentoo-gnu x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
- What I was doing when the application crashed:
I clicked on >File >Export Data...

- Custom settings of the application:
Compiled with gcc 4.7.3 on Gentoo with these CXXFLAGS:
-O1 -pipe -g -ggdb -fno-omit-frame-pointer

Crash does not happen when turning off optimization (-O0). It also does not
happen when starting Kalzium with the --sync switch. In each (compiler)
configuration I tried so far, the crash either happens always or never.

The crash can be reproduced every time.

-- Backtrace:
Application: Kalzium (kalzium), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
