--- Comment #4 from Sven Eden <sven.e...@gmx.de> --- I have resolved my issue: Nothing I found on the internet worked. Then I stumbled about a several year old post, where someone on a Kubuntu system suggested to purge sonnet. So I unmerged (deinstalled) kde-frameworks/sonnet-5.90.0 from my system. As several other packages where linked against /usr/lib64/libKF5SonnetCore.so.5.90.0 and /usr/lib64/libKF5SonnetUi.so.5.90.0, the Gentoo build manager Portage kept those libraries nevertheless. There is a special install target to rebuild those packages ("emerge @preserved-rebuild"), which I ran. It did not only re-install sonnet, but also rebuilt kde-frameworks/ktextwidgets-5.90.0 kde-apps/kpimtextedit-21.12.2 kde-apps/kanagram-21.12.2 kde-plasma/kdeplasma-addons-5.24.0 kde-plasma/kmenuedit-5.24.0 kde-plasma/plasma-desktop-5.24.0 kde-apps/libksieve-21.12.2 kde-apps/messagelib-21.12.2 kde-apps/ktp-text-ui-21.12.2 kde-apps/parley-21.12.2 kde-frameworks/khtml-5.90.0 kde-frameworks/ktexteditor-5.90.0 and finally: kde-apps/kmail-21.12.2 The next time I tried to start Kontact, it showed up, and opened dozens of windows with an empty e-mail to the person I originally tried to reply to. After I had closed (and discarded) all these windows, everything seemed to be fine. I am still testing, but it seems Kontact is back to normal. -- You are receiving this mail because: You are watching all bug changes.
