Summary0003576: gnunet-publish can't publish a sub-directory named "gnunet"
DescriptionWhen publishing a directory using gnunet-publish if a sub-directory is named "gnunet" (and only "gnunet" seems to do this) then instead of the directory being added to the gnunetdirectory as "gnunet", if you're lucky it is added as NULL, and shows up as such when you try gnunet-directory on the resulting gnunetdirectory. using gnunet-download -R -o something.gnd produces a 'something' directory, but the subdirectory within it named "gnunet" is given the name of its CHK instead. Any other files in "something" will retain their names and save as something/whatever.txt or the like.

If you're unlucky, gnunet-publish just crashes unconditionally whenever it tries to publish a directory whose sub-directory is named "gnunet" and again, renaming that directory before publishing causes no problems or crashes.
Steps To Reproducesee attached shell script
Additional Information$ gdb --args gnunet -V something/

I've tried but failed to reproduce the issue (I can publish, and download, using the provided shell script).

Nevertheless, looking at the crash, I can see why there might be an NPE, and I've fixed that in SVN 34549.

However, that doesn't explain the 'NULL' name you get for the 'gnunet/' directory.
Please let me know to what extend the attached patch helps. As I cannot reproduce the issue, more information would be helpful.

I'll give it a shot sure.

That fixed it, yeah.

NPE fixed the problem

That doesn't quite explain the behaviour you mentioned with the 'gnunet'-name specific stuff, or the name of the dir being 'NULL', or it being non-deterministic. As it was non-deterministic, maybe you can run it a few (100) times on your system to see if there is a 2nd issue? (and if so, re-open)? Thanks!
