Did you forget the "bt" call?
I don't see a debuginfo rpm for nxagent in http://packages.x2go.org/epel/6/main/x86_64/rpms/nx-libs/ but can you try to install http://packages.x2go.org/epel/6/main/x86_64/rpms/nx-libs/nx-libs-debuginfo-3..., restart gdb and issue the bt command, please?
Uli
Thanks!

Did you have a look at the abrt-cli command? It stroes coredumps in some crash directory. So you might find some more.
