The above causes:

Although in my tests it doesn't..

This is hopefully fixed by:
http://hg.dovecot.org/dovecot-1.2/rev/d00abdaf9df2

So you get a core dump? Could you print a few values:

fr 6 (or whatever starts giving the right values)
p *ctx
p *ctx.ns
p ctx.patterns[0]
p ctx.patterns[1]
p ctx.patterns[2]
p match
p ns_prefix
p p

The ctx.patterns values are the most important ones I think.
