The window is on screen for less than a second and then this happens: > kmail: symbol lookup error: /usr/lib/x86_64-linux-gnu/libKF5MessageCore.so.5: undefined symbol: _ZNK5KMime5Types7Mailbox13prettyAddressEv
I can confirm the bug for KDE Neon on Ubuntu 16.04 (x86_64): ... org.kde.akonadi.ETM: Fetch job took 397 msec org.kde.akonadi.ETM: was collection fetch job: collections: 112 org.kde.akonadi.ETM: first fetched collection: "Lokale mapper" org.kde.akonadi.ETM: collection: "[Gmail]" org.kde.akonadi.ETM: collection: "Drafts" org.kde.akonadi.ETM: collection: QVector() org.kde.akonadi.ETM: Fetch job took 475 msec org.kde.akonadi.ETM: was collection fetch job: collections: 7 org.kde.akonadi.ETM: first fetched collection: "Search" org.kde.akonadi.ETM: Fetch job took 1697 msec org.kde.akonadi.ETM: was item fetch job: items: 16119 org.kde.akonadi.ETM: Fetch job took 1710 msec org.kde.akonadi.ETM: was item fetch job: items: 0 org.kde.akonadi.ETM: Fetch job took 1991 msec org.kde.akonadi.ETM: was item fetch job: items: 22 org.kde.akonadi.ETM: Fetch job took 1962 msec org.kde.akonadi.ETM: was collection fetch job: collections: 0 kmail: symbol lookup error: /usr/lib/x86_64-linux-gnu/libKF5MessageCore.so.5: undefined symbol: _ZNK5KMime5Types7Mailbox13prettyAddressEv $ kmail --version kmail2 5.4.3 $ apt-show-versions | grep kmail kmail:amd64/xenial 4:16.12.3+p16.04+git20170310.0516-0 uptodate $ apt-show-versions | grep libkf5messagecore libkf5messagecore5:amd64/xenial 4:16.12.3+p16.04+git20170320.0112-0 uptodate The bug appears since about 2 weeks now. It makes KMail unusable under current KDE Neon (dev/stable).
It seems that some dependencies of Qt and/or KDEPIM are wrong for the Neon dev/stable distribution: See https://www.mail-archive.com/kde-bugs-dist@kde.org/msg129087.html
Well, now I am getting the slightly different: symbol lookup error: /usr/lib/x86_64-linux-gnu/libkmailprivate.so.5: undefined symbol: _ZN10MailCommon24FavoriteCollectionWidget19prefereCreateNewTabEb
just needs a rebuild but we've moved around machines and now added locale so the rebuilds are progressing slowly
kmail runs fine for me now
