Description Christoph Feck 2010-09-23 15:49:02 UTC

Application: workout (0.9.50)
KDE Platform Version: 4.5.69 (4.6 >= 20100920) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.7-0.2-desktop i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:

I compiled the KDE4 version of Workout, and just running it, causes this crash in Marble plugin. KDE from trunk.

The crash can be reproduced every time.

-- Backtrace:
Application: Workout (workout), signal: Segmentation fault

Comment 1 Christoph Feck 2010-09-23 15:50:06 UTC

Adding Volker, author or Workout.

Comment 2 Volker Lanz 2010-09-23 17:41:14 UTC

Quoting from #marble a few weeks ago:

19:39 < Torch> deleting the starsplugin helps
19:46 < Torch> hjain: $ rm /home/kde-devel/kde4/lib/kde4/plugins/marble/StarsPlugin.so
19:48 < hjain> idis_: I think this problem is related to cmake. The previous StarsPlugin.so was not replaced by the newer one. But I am not sure.

The crash does not happen on my 4.5.1 installation where I mainly develop.

Comment 3 Christoph Feck 2010-09-23 22:11:24 UTC

Right, deleting StarsPlugin.so works, but on next installation of Marble, it is installed again, so it wasn't an old file lying around.

Comment 4 Dennis Nienhüser 2010-09-26 09:44:55 UTC

SVN commit 1179732 by nienhueser:

Replace the c-style cast with a dynamic_cast and check its result. You cannot rely on the paint device being the marble widget, this is not true if the widget is disabled, for example.

Comment 5 Christoph Feck 2010-09-26 13:29:54 UTC

Thanks, after this commit, workout no longer crashes.

Comment 6 Dennis Nienhüser 2010-09-26 14:30:28 UTC

Great, thanks for testing. Trunk doesn't have this code part, so no backport is needed.

Comment 7 Dennis Nienhüser 2010-09-26 14:30:49 UTC

Great, thanks for testing. 4.5 doesn't have this code part, so no backport is needed.
