Description quamis 2014-08-20 19:12:05 UTC

when running from the console i get this: 
$ digikam 

Object::connect: No such signal org::freedesktop::UPower::DeviceAdded(QDBusObjectPath)
Object::connect: No such signal org::freedesktop::UPower::DeviceRemoved(QDBusObjectPath)

digikam: symbol lookup error: digikam: undefined symbol: _ZN10KFaceIface8IdentityD1Ev



I've just installed opensuse, and I have no idea how to make it show the crash handler app (as it did on Ubuntu) to be able to send a proper stacktrace

digikam: symbol lookup error: digikam: undefined symbol: _ZN10KFaceIface8IdentityD1Ev

==> It's a binary compatibility issue with libkface shared lib used by digiKam to perform face recognition.

Typically libkface installed is not the last version. It's a packaging problem from your distro. Please report as DOWNSTREAM problem...

Not reproducible since digiKam core do not depends anymore of libkface
