After upgrade from gdbm-1.8.3-r3 to -r4 qpopper's popauth is unable to open database any more with the following error: 1257 etc # popauth -list popauth: unable to open POP authentication DB /etc/pop.auth: Invalid argument (22) [1046] Relevant code from qpopper's ./popper/popauth.c: db = gdbm_open ( auth_file, 512, GDBM_READER, 0, 0 ); if ( db == NULL) adios ( HERE, "unable to open POP authentication DB %s:\n\t%s (%i) [%i]", auth_file, strerror(errno), errno, __LINE__ ); Nothing special here, so I'm unsure why upgrade broke database. Does upgrade on -r4 works for anybody ?
