Bernhard, Please try the attached patch. Over here, it builds kopete 17.08.3-1 from unstable against the linphone libraries in experimental. I hope it allows Linphone to enter unstable.
The patch also applies to kopete 18.04.2-1 from experimental (with fuzz), but still throws the error. If it is okay with you, I will leave that for another day. Please let me know how it goes. Thank you! Kind regards, Felix
