rdesktop freezing/crashing on Ubuntu core (Mint) over Cisco VPN

I'm having some instability issues with rdesktop. I've had these issues
since I started using it. I've downloaded the source for 1.6, compiled and
installed it.

If I run it with -a 8, I usually can keep it up longer without as many
problems. At 16 I get a lot of on screen garbage after a few minutes, and
have to quit and restart just to read what the screen says. I really don't
know much at all about rdesktop or any of the low level networking that
goes with it.

I'm running basically a stock Mint 5.0 KDE edition:
Linux wanderer 2.6.24-23-generic #1 SMP ... i686 GNU/Linux
Intel(R) Core(TM)2 CPU         T5300  @ 1.73GHz

on an HP/Compaq Presario v6000.

I know I could be running a 64 bit kernel, but I'm not.

Here's a sample of a normal session:

happens a lot. Although sometimes it just crashes. */

Maybe someone can help? I've seen several reports of buggy behavior like
this. I've not really done much in the way of coding in Linux.

Thanks,
Brian
