I'm not able to reproduce this problem, so I'd like your help to get a 
backtrace, if you are willing:

1. Download [1] (this is a build of the 1.7.1-1 XWin server but with debugging 
symbols unstripped)
2. bunzip2 XWin-1.7.1-1.unstripped.exe.bz2 to uncompress it
(you may need to install the bzip2 package)
3. gdb --args ./XWin-1.7.1-1.unstripped.exe -clipboard
(you may need to install the gdb package)
4. Wait for the '(gdb)' prompt, type 'run'
5. In another terminal window, do your ssh, start firefox and do whatever you 
do to make the crash happen. You should get another '(gdb)' prompt, type 'bt full'
6. post the output
