Is this http://bugs.kde.org/show_bug.cgi?id=128854 worth to be integrated into the Gentoo patch set for KDE ?
I fixed it for the split build kde-base/konqueror immediately. For kde-base/kdebase I will attach the patch and it might be added to the next revision bump.
Created attachment 98018 [details, diff] kdebase-3.5.4-konqueror-clean-history.patch Patch to solve the issue for kde-base/kdebase.
Patch won't be applied to kde-base/kdebase due to the fact that kde 3.5.5 is on its way. Closing as fixed as it is already applied for kde-base/konqueror split ebuild.
