As said on irc (#mageia-kde)  i've got that when i was upgrading on cauldron :

rpm -qp --requires lib64db5.2-5.2.42-2.mga3.x86_64.rpm 
filesystem >= 2.1.9-18
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(CompressedFileNames) <= 3.0.4-1
libc.so.6()(64bit)
libc.so.6(GLIBC_2.14)(64bit)
libc.so.6(GLIBC_2.15)(64bit)
libc.so.6(GLIBC_2.2.5)(64bit)
libc.so.6(GLIBC_2.3)(64bit)
libc.so.6(GLIBC_2.3.4)(64bit)
libc.so.6(GLIBC_2.4)(64bit)
libpthread.so.0()(64bit)
libpthread.so.0(GLIBC_2.2.5)(64bit)
libpthread.so.0(GLIBC_2.3.2)(64bit)
rtld(GNU_HASH)
rpmlib(PayloadIsLzma) <= 4.4.6-1

Where lib64db5.2 is required by rpm (lib64rpm3) to get installed, but 
filesystem can't be installed since rpm was not updated to provide this 
filesystem :)
