Application: lokalize (1.4)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
I was trying to open an invalid .po file. Seems like the header was not properly written.

The crash can be reproduced every time.

-- Backtrace:
Application: Lokalize (lokalize), signal: Segmentation fault
