Found it! There is a problem with gnunet-insert and files smaller than 1k
(essentially, the root-node that is generated was wrong). Fixed in CVS.

I haven't been able to reproduce that yet. You should get a core-dump in that
case. Just run "gdb `which gnunet-gtk` core*" and type in "ba" to get a stack
trace. That should give us an idea where to start looking.

Well, you were 50% wrong :-)

Usually, a core-dump is a great help if it segfaults. Otherwise, activate
debug statements (debugging.h) and we can eventually see something.

stare at sources (Linus approach), printf (lots), gdb (segfault only, at
least that's how I keep it) :-)
