Assuming you're talking about an entire-GUI freeze (as in, you can't
even see the mouse moving when you move it), my first guess would be a
video driver problem.

Do you mean after the reboot, or before?  If before, I partially take
back what I just said (but not really).

I've seen this occasionally too; I'm relatively sure it's harmless

This is a bug in librsvg; harmless.

These are both from the desktop menu code (from the latter, I assume
you're using the Xfce Menu plugin for the panel); again, harmless.

I'm strongly feeling that this is a video driver problem.  Are you using
the open-source nv driver, or the binary/proprietary nvidia driver?
Whichever you're using, trying the other one might help in figuring out
where the problem lies.

Version: GnuPG v1.4.1 (MingW32)
