Test setup: Mounted sshfs storage in which albums and sqlite DB is stored. When importing from SD card storage, the UI freezes, making the application unusable. Reproducible: Always

This problem have been fixed in recent release. Try with last 4.12.0. Gilles Caulier
digiKam 4.12.0 is out : https://www.digikam.org/node/741 We need a fresh feedback using this release please... Thanks in advance. Gilles Caulier
Moved the SQLite DB locally (synced to the server via OwnCloud). Updated to 4.12.0. I haven't meet any freezes so far. Plus the whole workflow is much more fluid. I consider this solved in 4.12.0. Also for anyone else in the future: DON'T store the database file on a remote server if you use SQLite.
