SLES 11 SP2 or SLED 11 SP2 is new-fresh standard installed (ext3, one default user), + mc, gcc.
When install was chosen Russian language and US keybord.
if you rename a file (F6) whose name consists of three letters, first letter is lost and is equal to the third

X11 or not, it does not matter;
anyone user, any file, any rights, everywhere
for example:
*** F6 xyz ->zyz
The above bug error rewrites root rights.

Moreover, sometimes lost third from the end letter and is equal to the end letter.
Viewing in mc tar.gz
