Freenx on Centos 6.4 can't disconnect, libc fault

[Simon Guerrero]

Running freenx.x86_64 v0.7.3-9.4.el6.centos from "extras" repository on Centos 6.4. I'm using the latest Nomachine 4 front end in "ssh" mode.

When I try to close the window, the "disconnect or logout" message is shown. Clicking either button does nothing.

Upon investigation, the following message appears in /var/log/messages:

kernel: nxclient.bin[2507] general protection ip:7fa319a4d7be sp:151e8966c20e4d30 error:0 in libc-2.12.so[7fa319a1b000+18a000]

The only way I can exit is to log out from within the NX session -- thus losing my session until the next login.
