Please try again. I fixed a million things in the spectrum code. For example, that widget only shows up when there is acutally data for the widget to display. If you cannot confirm I will close this as fixed. For me it works. Just updated sources a few minutes ago and recompiled kdeedu and it still crashes. Still crashes using todays SVN. But this time I get a little bit different backtrace.

But I have 0.0 clue, how this can happen. I clicked on those buttons a hundred times since you reported, it never crashed. Same for others... Did you do a "make install" after "svn up"? Did you try to "make clean"?
Please tell me which distro you are using, which Qt, which KDE-version. I will ask more people to try to reproduce this.
Yup. I did try with clean kdeedu sources and with clean kdeedu build dir. I'm using Gentoo Linux (64-bit AMD64 mode). Qt is 3.3.4 from qt-copy from KDE SVN, KDE is 3.5 trunk from SVN. Backtrace from Martin Pfeiffer, also a 64-bit machine, but running in 32-bit mode.

Ok, this means three persons can reproduce this crash, all on amd64. All non-amd64-machines cannot reproduce this. I have no access to a amd64-machine so I don't know what to do about it... Carsten I changed quite a lot code in the last couple of weeks including the deleting of the spectrum. Would you please check if it is still crashing? Just updated the code and recompilled and it stil crashes :( Created attachment 12013 [details]
hacky work around (1)
Since the what from what I understand the crash happens only happens on amd64
and the stacktraces look severly corrupted, I think it could even be a compiler
bug (would not be the first for that plattform).
The patch is not a real solution, but at least on my amd64 system the crash
vanishes with the small modification

sorry, Kalzium shows you a abundance of 12ppm on every element? Please report
that as a bug as well.
SVN commit 509359 by pino: Ok, here we hare. I'm backporting almost all the improved Detail Info Dialog from kalzium trunk (ie kde4) to the 3.5 branch, as last resource to have a Detail Info Dialog really working without any bug and/or crash. So, please please, please, reporters and readers of bug 109035, update your kalzium from kdeedu 3.5.x and say whether it works well without the reported crash. In case, we'll close this bug. CCBUG: 109035 M +103 -106 detailinfodlg.cpp M +26 -23 detailinfodlg.h M +2 -0 orbitswidget.cpp M +1 -0 spectrumwidget.h I have compiled and installed newest version from Subversion and stressed it for about 10 minutes going back and forth elements in all these tabs (Spectrum, chemical data, Energies) and couldn't reproduce it.
