acroread9 would not come up on 8.1/i386: 'RSException'

[Mikhail T.]

Hello!

acroread9 would not come up on this newly-built 8.1 system:

    s at s:~ (277) acroread9

    (process:70135): Gtk-WARNING **: Locale not supported by C library.
             Using the fallback 'C' locale.
    terminate called after throwing an instance of 'RSException'

The linux-base is "f10", both "special" filesystems are mounted:

    linprocfs on /usr/compat/linux/proc (linprocfs, local)
    linsysfs on /usr/compat/linux/sys (linsysfs, local)

Please, advise. Thanks! Yours,

    -mi
