Define Custom Bank Messages... crashes Logic Pro X 10.0.5

Question

Hi all,
Having a devil of a time setting up patch names for my Proteus 2000 in Logic Pro X 10.0.5. The Proteus 2000 requires a custom bank message format to access all of its banks over MIDI, so in the MIDI Environment I select its multi-instrument and then Options -> Define Custom Bank Messages.... EVERY time I do this Logic crashes, the custom bank messages window never opens. (The same thing happens if I right-click the multi-instrument and select Define Custom Bank Messages... from the contextual menu.) (Partial crash log below.)
I have tried switching off my MIDI modules and disconnecting my MIDI interface, just to see if it's a hardware issue, but to no avail. I have got to this window before, in an earlier version of Logic Pro X, so I'm wondering if it's a bug with 10.0.5. Any more suggestions of things to try?
(I'm running a 2012 Mac Mini with Mac OS X 10.8.5, Logic Pro X 10.0.5, and a Cakewalk UM-2G MIDI interface.)

You are not the only one. I'm trying to Define Custom Bank Messages for my Yamaha Motif-Rack ES and am getting the same problem. To me this is a MAJOR bug!!! All of my tone modules are useless with this program at this point. grrr

Do I dare not buy anymore Apple backed DAW software?? They is an essential part of functionality for someone who uses external devices.
