Description

The following Python script doesn't work as expected:

from svn import core, fs, repos

def repro(pool):
  repos.svn_repos_open('no-repos-named-that-way', pool)

def main():
  print core.SVN_VER_MAJOR, core.SVN_VER_MINOR, core.SVN_VER_MICRO
  core.run_app(repro)

if __name__ == '__main__':
  main()

On Windows, the script reports this:

1 1 1
Traceback (most recent call last):
  File "C:\java\rsvn\recipe.py", line 11, in ?
    main()
  File "C:\java\rsvn\recipe.py", line 8, in main
    core.run_app(repro)
  File "C:\Python23\lib\svn\core.py", line 33, in run_app
    return apply(func, (pool,) + args, kw)
  File "C:\java\rsvn\recipe.py", line 4, in repro
    repos.svn_repos_open('no-repos-named-that-way', pool)
SystemError: null argument to internal routine 


On Linux, the actual Exception is different:

   $ ./test.py    1 2 0
   Traceback (most recent call last):
     File "./test.py", line 12, in ?
       main()
     File "./test.py", line 9, in main
       core.run_app(repro)
     File "/usr/lib/python2.3/site-packages/svn/core.py", line 37, in run_app
       return apply(func, (pool,) + args, kw)
     File "./test.py", line 5, in repro
       repos.svn_repos_open('no-repos-named-that-way', pool)
   libsvn._core.SubversionException: ("Can't open file
'no-repos-named-that-way/format': No such file or directory", 2)

This is a showstopper for RSVN, as most of the time I cannot guess what is
wrong, and cannot continue development.
