Hmm...
[root@kindle bin]# readelf -d ./rdesktop

Dynamic section at offset 0x1d4f8 contains 27 entries:
Tag Type Name/Value
0x00000001 (NEEDED) Shared library: [libcrypto.so.1.0.0]
0x00000001 (NEEDED) Shared library: [libX11.so.6]
0x00000001 (NEEDED) Shared library: [libgcc_s.so.1]
0x00000001 (NEEDED) Shared library: [libc.so.6]

Let me try and isolate those to the system ones.

edit: I did manage to get it reboot X one time with multiple rapid relaunches but that aside even hardcoding LD_LIBRARY_PATH=/usr/lib:/lib (just to be sure) rdesktop runs from those libs.

I would simply suggest running yours:
LD_LIBRARY_PATH=/usr/lib:/lib /mnt/us/extensions/rdesktop/bin/rdesktop blah...
if you think library pollution is the issue.

HTH
