Thumbnails not shown in albumview

[Rüdiger Härtel]

Hello,

just for the record:

in November 2017 there was this thread
  https://mail.kde.org/pipermail/digikam-users/2017-November/025721.html

It is excatcly the same situation for me.
* No thumbnails in album view
   thumbnails and images are shown in all other views, ie. timeline, dates ...
* not able to create new albums
    the message is: "Fehler beim Erstellen des Ordners file:///test01"

I am using KDE NEON
digikam:        5.7.0
KDE framework:  5.41.0
QT              5.9.3


I uninstalled digikam (apt remove) and used the appimage.
Everything is working now. However, it might be worth to resolve this 
behaviour.

Regards,
Rüdiger
