My N800 has developed a problem with opening more than a couple of applications at once. Sometimes it works, sometimes nothing happens, occasionally it reports "Internal error. Application 'Web' closed" (or whatever the application is), and refuses to open it.

Right now, I have the latest VNC and gaim running, and
I get the aforementioned error trying to open Web or XTerm.

If I quit VNC, I can launch XTerm.

If I then do /usr/bin/browser (guessing at how to launch it), I get 'segmentation fault'.

Any suggestions? Is there a log I can look for that would tell me what the problem is?
