-- Information about the crash:
- What I was doing when the application crashed:
I was closing the application through the "Close" button after updating translation language packages from
"svn://anonsvn.kde.org/home/kde/trunk/l10n-support/it/summit/messages"
and  "svn://anonsvn.kde.org/home/kde/trunk/l10n-support/it/summit/docmessages"

The crash can be reproduced every time.

-- Backtrace:
Application: kdesvn (kdesvn), signal: Segmentation fault
