What QT version are you using? This may be a known bug , already fixed in qt-copy, and Qt 4.4.4 / 4.5 (bug 174065)
4.4.2 with some custom fixes of gentoo linux.
Can I get the list of Gentoo patches? (It may include the patch which fix this issue or not). Thanks :)
In qt-gui I see only these: 0254-fix-qgraphicsproxywidget-deletion-crash.diff qt-gui-4.4.0-scrollbars.patch qt-gui-designer-4.4.1.patch
This crash should be fixed by the patch named: "0256-fix-recursive-backingstore-sync-crash.diff"
*** This bug has been marked as a duplicate of bug 174065 ***
Please report this problem to the gentoo people. And tell them to subscribe to the kde-packager list.
