Finally, i investigated, and this is a problem of VMware... :-( not of Ubuntu.

Here it is described:
https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/1509729

The solution:
https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/1509729/comments/7

i.e. :
"""
The file /etc/ld.so.conf.d/LD_LIBRARY_PATH.conf contains the line /usr/lib/vmware/lib/libglibmm-2.4.so.1
After delete this line the path from file "LD_LIBRARY_PATH.conf"
and execute the command
# sudo ldconfig
all works !
