digikam slow or hang on startup

[Andrew Goodbody]

I compile digikam from source. My latest build from a few days ago is 
now taking ages to start, or very possibly hangs.

My previous build was fine, but that was a few weeks ago.

Running under gdb, I gave it ten minutes or so, then pressed Ctrl-C and 
'bt' to get the below stack trace.

Local files and sqlite database.
