Bug Description

I started a vnc session in terminal with the following command:
$vncserver :1 -geometry 1220x740 -depth 16

the content of .vnc/xstartup is:
#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
### End of file

I connected with vnc client (vinagre) in other machine, and everything is running well, I can see Ubuntu desktop fine, etc. Then I tried change the icon of any launcher that I have in my desktop, and suddenly Nautilus crash with several glibc errors:

### end error report ###

This error is ocurring with others applications, (always using vnc connection) but this is most easy way to reproduce it.

I have checked this errors with vnc4server is not ocurring with Ubuntu 10.04 and Ubuntu 11.04, only happen with ubuntu 10.10.

Thanks in advance.
