Thanks for you reply. Looks like it indeed. The only confusing bit left was the apparent "crashing" of the release- upgrade dialog, causing the startup of apport and this bug report in the first place.
A dialog with "we cannot properly convert your sources.list, please fix it manually" and no crash would've been better IMHO. But I don't care enough to reopen this ticket.
