Hi, could you please provide a fix for this bug please? :)
Thanks to Danilo Spinella, done for 15sp3/libyang. Reassigning to openSUSE maintainer.
When done, please reassign to firstname.lastname@example.org.
Might be that libyang in Factory is not affected at all. Could you please help us by stating this fact in *.changes file?
