In DigiKam, go to "Help" -> "Components Information" and
post the output on the mailing list.

Mine looks like:

To enable debug output: Start the programm "kdebugdialog",
search for "digikam" and select all checkboxes. Click "OK"
and start digikam from your terminal.

Applying title ("mytitle") and caption ("mycaption"), I get
the following debug output:
