Comment 1 Dario Andres 2009-07-07 16:48:00 UTC

This looks related to bug 198702, but I can't be sure.
Thanks

Comment 2 Aaron J. Seigo 2009-07-07 22:14:42 UTC

yes, they are the same bug; however, we need a full backtrace with line numbers to know what's going on there exactly. as seen in 198702, that report was against some odd/old version of Qt.

James: if possible can you upgrade to Qt 4.5.2 as well as install the debug packages for qt, kdelibs and kdebase and reproduce?

I am using QT-COPY and I upgraded that last night.  Or, would it be better if I used the Qt-4.4.2 release to test 4.3?

So, that was the easy part.  I have no idea how to reproduce the crash.  It was just a random crash while configuring Plasma on KDE-4.3 RC.

I can tell you that I had another problem with Plasma.  I configured additional Panels and logged out.  When I logged back into a KDE-4.3 session, the settings were not remembered correctly.  Perhaps that is where the problem is occurring.  I can't reproduce that problem either.

All that I can say for sure is that I configured (IIRC) 2 Panels and then clicked the DeskTop to configure a third and it crashed.

No, it is better to use Qt4.5.x+ or Qt-copy (or kde-qt at git). Thanks

I appear to have made a typo.  This should have been:

Comment 6 Dario Andres 2009-08-19 21:21:46 UTC

BTW, qt-copy is being killed (and it was outdated already). Switch to kde-qt.git or use the distribution-package for Qt4.5.2
Thanks

Comment 7 Dario Andres 2009-09-01 23:01:45 UTC

This could be related to bug 205560 too. Thanks
