Thanks Uwe,

All backtraces indicate a problem with Exiv2 multicore/Multi-threads
processing. This use case problem must be reported to Exiv2 bugzilla. There is
no reason for these kind of dysfunctions while Exiv2 read or write from/to
image files metadata.

>the gentoo package media-gfx/exiv2 isn't able for multi-core support. a friendly soul has checked the code :-) (thank s to firefly)

How this information have been verified exactly ?

So the only way to multi.core support is the switch in digikams maintenance
dialog - right? I don't use the switch because I have to work while digikam
makes the maintenance....

Yes. Disabling multicore support will run maintenance tools in a single CPU. It
will be interesting to see if the Exiv2 dysfunctions are reproducible in this
case.

Of course, One single core to run maintenance tools will be slower, as
expected.
