Sentry Crash Report:

Description Manfred Rebentisch 2012-04-02 15:11:28 UTC

Application: kate (3.8.1)
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:

Switch to the kate window and scroll down in a html file very fast (with the mouse on the right scrollbar).

Sometime it is not possible to access the last lines of the file (not only html files), sometime kate crashs.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault

Comment 2 Manfred Rebentisch 2012-04-03 08:11:25 UTC

Hello Dominik,
I do the git clone and build process again, along the description of http://kate-editor.org/get-it/

The kate editor shows version 4.8.1, not 4.8.2 - is that ok? If not: how can I get 4.8.2 ?

Thank you
Manfred

Comment 3 Dominik Haumann 2012-04-03 08:30:25 UTC

Kate usually is shipped with KDE. For this reason, Kate builds its version from KDE. So when you start Kate under KDE 4.8.1, it will always say Kate 3.8.1. If you started it in KDE 4.6.0, it would say Kate 3.6.0, even though you compiled it from sources.

In other words: if you compiled from git, you have the newest version, no matter what your About-dialog says :-)
