Remco,
Apologies for the delay.
I'm currently using the following:
Kubuntu 11.10
Linux kubuntu64 3.0.0-16-generic #28-Ubuntu SMP Fri Jan 27 17:44:39 UTC
2012 x86_64 x86_64 x86_64 GNU/Linux
KDE version 4.7.4
digikam v 2.1.1 (standard stock install from Kubuntu repositories)
I have updated some packages over the last week - but I'm not sure if
any are related to digikam. In fact, I couldn't tell you what they
were. Do you know how to check for the most recently installed packages
by date? I could then list them out for you.
I did suffer a possible power failure over the weekend whilst I was away
- I don't really know other than I came back to the house on Sunday and
the PC had rebooted, so something definitely went wrong. Digikam was
open at the time of the crash - maybe that corrupted the database?
No new disks installed/used. No changes to Digikam made as far as I know.
How can I tell you what external libraries are installed? Apologies -
but my knowledge is limited there. If you can supply a command to run,
I can easily post you a list of them.
Sorry that I can't supply more information - but if you can let me know
any commands to run for you - will get right back to you as soon as I can.
Thanks.
Mark.

I had given up on using templates completely because the documentation does not adequately describe their use and application ( it is actually incorrect, indicating a preference pane that no longer exists).
