[Digikam-users] Too slow metadata writing with exiv2 and Nikon - how to solve?

[Barberet]

Hello,

I'm facing the same issue. I've upgraded to digikam 1.3, but I have the 
same 
problem (normal given problem description).
I'm using kubuntu 10.04 upgraded to kde 4.4.4.

I've tried following without success:
1- Install libexiv2-0.20 that fix the bug, from sources. This installed 
/usr/lib/libexiv2.so.9
2- Using apt source, I've recompiled libkexiv and digikam. However, ldd 
shows there are still linked with libexiv2-0.19 (/usr/lib/libexiv2.so.6)

I gave up at this stage with this method.

I've then seen that a new debian version of libexiv2-6_0.19 has just been 
released that include the nikon patch.

I installed the .deb, my /usr/lib/libexiv2.so.6 is updated, but digikam is 
still very slow....

I'm stuck... What's wrong ?

best regards

Vincent
