[Digikam-users] Loosing all Metadata when editing

[Max Bedacht]

When I run Digikam in a terminal window there is a lot of output to the
window. Is that the debug info that you mean? I'm not too familiar with this
kind of stuff.

I have been trying to isolate conditions where the problem is occurring and
I am getting bogged down in too many possibilities.

I have converted to ppm and png and dng and get different results. I have
used the Digikam converters and stand alone and seem to get different
results.

I am going to try to build a matrix of conversions x results and I will post
them when I can.
