Backtrace? :-)

Comment 3 Martin Samek 2016-08-07 21:17:02 UTC

Not a gdb guru, here is some output. Is it correct that Digikam 5 loads libOt4Test.so.4 <

I can confirm this bug. It's always reproducible. Here is my backtrace:

(In reply to Martin Samek from comment #3)
> Not a gdb guru, here is some output. Is it correct that Digikam 5 loads
> libOt4Test.so.4 <

This is almost certainly the cause - loading both Qt 4 and Qt 5 at the same time will cause a crash due to the symbol collisions.

What's the output of lddtree /usr/bin/digikam ? (lddtree is from app-misc/pax-utils if you don't already have it)

Looks like media-libs/opencv is built with USE="qt4". We should check if -qt4 is enough, or if +qt5 is required too.

Comment 8 Frank Noack 2016-08-10 17:10:50 UTC

I have rebuild media-libs/opencv with use=-qt4 and digikam works fine, use=qt5 didn't change anything.

Thanks a lot for testing.

media-libs/opencv[-qt4] is now enforced in digikam-5.1.0.
