Hi walt. Next time run pan with gdb and do a backtrace. Also do an
"export G_DEBUG="fatal-warnings" before running it.

Very disappointing:

I think I need a breakpoint at cairo-surface.c:1287, but I'll need to
stop and review gdb a bit first.

Meanwhile I found a 100% reproducible way of hitting the assertion :)

I've been using via ssl since you added that feature to pan.
If I use pan's cert editor to delete gmane's cert and restart pan, I
get a popup from pan asking me to (re)accept gmane's cert (because I
just deleted it, of course).

When I click 'accept' on that dialog, pan immediately hits the assert
that I've pasted above.  Never fails.

Can anyone else reproduce?

BTW, Duncan, I'm still using gtk2 to build pan.  Maybe gtk3 will work
better :)  I'll try it.
