xfdesktop segfaults when compiled with menu support on svn 26052. everything works fine on svn 25944.
this is a strace of the xfdesktop segfault: http://www.wujiman.net/xfdesktop.log
strace is useless; please post a gdb backtrace. Though I suspect you've just found a dupe of bug #3079.
i've just updated to r26054 and it works just fine.
Coincidence - only changes between those 2 revs are a translation update in xfdesktop and some change to xfwm4.
That's what surprised me as well. I've recompiled xfdesktop with --enable-debug=yes to get that backtrace but it evidently solved my problem. So I can probably reproduce the problem when I disable debugging again but that won't help much. Anything I can do to help solve this?
Not that I can think of...
