Bug 315494

I get this error on startup:
Failed to update the database schema from version 6 to version 7. Please read the error messages printed on the console and report this error as a bug at bugs.kde.org.

console logs:
QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in use, all queries will cease to work.
digikam(2689)/digikam (core): No DB action defined for "UpdateSchemaFromV6ToV7" ! Implementation missing for this database type. 
digikam(2689)/digikam (core): Attempt to execute null action 
digikam(2689)/digikam (core): Schema update to V 7 failed!

After closing the error window, I get the following logs:
"/org/freedesktop/UDisks2/drives/WDC_WD5000AADS_00L4B1_WD_WCAUH1354910" : property "DeviceNumber" does not exist 
"/org/freedesktop/UDisks2/drives/WDC_WD5000AADS_00L4B1_WD_WCAUH1354910" : property "Device" does not exist 
digikam(2689)/kdecore (services) KServicePrivate::property: Request for unknown property ' "X-KIPI-BinaryVersion" '
digikam(2689)/KIPI (loading) KIPI::PluginLoader::init: Plugin had an empty name or library file - this should not happen. 

the last two repeat multiple times. I do not see any albums in the digikam and cannot open any picture at all. 

Reproducible: Always

Steps to Reproduce:
1. build kdcraw and kipi from github
2. build digikam from github
3. start digikam
