I can't reproduce this with rev 890719. Can you tell us exactly which change triggers that and/or try with a more recent version? Thanks. I will build from trunk as soon as I have time; as for now, the crash is triggered by a change in the widget style (e.g. from Oxygen to cleanlooks) and happens when applying the change. In fact even a trivial change (e.g. Oxygen to cleanlooks, then back to Oxygen, just to activate the apply button) triggers the crash when clicking on the Apply button. I am on amd64 (as you can tell by the 64bit addresses in the backtrace) here are my (very conservative) CFLAGS: CFLAGS="-mtune=k8 -O2 -pipe -ggdb " It stills crashes for me with kmail built from trunk today. The backtrace is pretty much identical:

Out of curiosity, how do I get rid of the "<value optimized out>" in the backtrace?
Can anyone still reproduce this bug using an updated build? Thanks :) I'll get a new build as soon as I can and see if it works now. Fixed for me on 4.1.96 Thx Closing as WORKSFORME. Please re-open the bug report if you experience this again. Thanks :) *** Bug 181243 has been marked as a duplicate of this bug. *** Look at bug 181243 for another report in KDE4.2RC weird.. can it be a problem with different compilation options? Qt versions? as far as I can tell the reporter of bug 181243 and I should be using the same version of kde... Previously I could reproduce the crash every time I tried, but maybe there is something else that triggers it, I'm gonna investigate more. *** Bug 185070 has been marked as a duplicate of this bug. *** SVN commit 937301 by stefanek: Don't crash when changing KStyle and an empty tab is displayed.
