I have had the "MATE-panel crash at login" experience using Ubuntu-Mate 14.04 LTS
After installing Ubuntu-Mate 14.04 LTS, it worked perfectly. In my case what causes ( "MATE-panel crash at login" ) is cloning my operating system as a backup using gparted. Then when I restore the clone to same or different computer, MATE-panel would crash not at every boot, but very often. Enough times that I went searching if others had same experience and if there was a fix :P Using Debian and other Ubuntus I have always been able to backup and restore (and also clone my entire OS to other similar machines, like Lenovo R60, R61, T43) and had them run just as if they had been installed on them and not just copied over from an external hard drive using either gparted, and sometimes clonezilla; with no problems except maybe having to reconfigure wireless and printing. My point in posting this now, is that I have found out that by reinstalling the following packages, it fixes this problem for me and hopefully you if using Ubuntu-MATE 14.04 LTS. I will only be going to a new Ubunu-MATE when the next LTS is released, and know that there are others like me.
