On my 13.1/KDE 4.12.0 system, I received two Digikam updates today (Jan 14, 2014) from the KDE 4.12 Extras repo.
The first download, version 3.5.0-2.14 resulted in broken Digikam Editor - most menues are blank or missing key sub-menu items…
Later in the day, received ver 3.5.0-2.15, which did not seem to fix anything.
Not sure what is going on, but I reverted to Digikam 3.5.0-4.1 from the OSS repo and all seems back to normal, or should I limit that to the editor seems to be functioning again.
Version of packages between the OSS and Upstream repos is really getting confusing.
I don’t know if I moved to a later build or an earlier build, but for the moment , it works better.
