Description X Y 2019-07-23 07:17:31 UTC

Trying to start an application relying on libqt5-qtwebengine (like kontact/kmail or ksysguard) fails with the following error:

symbol lookup error: /usr/lib64/libQt5WebEngineCore.so.5: undefined symbol: FT_Palette_Select

I first encountered this after updating to TW 20190718, but I was away from home for all of July, so it could have been introduced in any release between Jul 1st and the release mentioned.
It is also still present in TW 20190721.

It is NOT present in the KDE factory packages.

By chance I'm currently booted into the latest Tumbleweed LiveCD (20190721), and QtWebEngine happens to work fine.

So this is likely caused by an incomplete upgrade or mixing incompatible repos/packages.

Please show the output of "zypper lr -d", and the exact versions of libqt5-qtwebengine and libfreetype installed:
rpm -qi libqt5-qtwebengine
rpm -qi libfreetype6

You were right, it was caused by a libfreetype6 package I still had installed from another repo - I don't even remember why exactly.

Good catch, clear case of PEBKAC.
