Marcel,

After to place some debug messages to JPEG2000 loader:

digikam(19367) Digikam::JP2KLoader::load: Init JPEG2000 API

identified                                                                      
digikam(19367) Digikam::JP2KLoader::load: Init JPEG2000 API

digikam(19367) Digikam::JP2KLoader::load: Scan JPEG2000 depth  

... I can see that Init JPEG 2000 API take a while... 


If i contunue my investiguations, i can see :

digikam(19606) Digikam::JP2KLoader::load: Init JPEG2000 API
digikam(19606) Digikam::JP2KLoader::load: Init JPEG2000 API: open stream
digikam(19606) Digikam::JP2KLoader::load: Init JPEG2000 API: decode
digikam(19606) Digikam::JP2KLoader::load: Init JPEG2000 API: close stream

... that Init JPEG2000 API: decode is the problem... here :
