I noticed the following bug in git-svn version 1.6.0.3 (svn 1.5.5):

"git-svn fetch" segfaults if I provide an incomplete svn.authorsfile config
file setting with account<-->email mappings. This happens if an unknown user
account is found in the Subversion log.

I should really provide more information:

I imported my Subversion repository in the past succesfully from my server
(svn+ssh protocol). Since I'm new to git (and still confused by the large
amount of git tools) I decided to start on a svnsync'ed copy of my repository
(file protocol) to avoid any harm. I added also some new config settings
including svn.authorsfile and fetching revisions started to fail.  The last
output was:

r38 = 4dca32e3d82a32206fd11545d4f270e118f51f12 (trunk@166)
        M       myproject/file

Revision 39 contained the unknown user account so I suspected the error
is related to an incomplete authors file.

I used following versions of Subversion:
Client: 1.5.5
Server: 1.5.3

After adding the missing account to the authors file it fetched all revisions,
called the garbage collector and stilled crashed with a core dump. Last
output:

Checked out HEAD:
  file:///home/jens/Subversion-Repository.synced/myproject/trunk r1700
Abgebrochen (core dumped)

This happened also after I removed the svn.authorsfile config setting.
My current settings:

[user]
  name = Jens Seidel
  email = jensseidel@users.sf.net
[color]
  diff = auto
  branch = auto
  interactive = auto
[svn]
  findcopiesharder = true
  rmdir = true

"gdb -c core" is useless, it just mentions the error occured in
"perl git-svn fetch" and there is no stacktrace (don't know how to
debug perl).

I removed now both [svn] options and it failed again. So it seems a problem
with file:// access while svn+ssh:// works well.

Are you sure this isn't the regular svn 1.5.x crash? Ie, does
compiling subversion with --disable-runtime-module-search fix it?

Huch? I follow the Subversion developer list and I'm not not aware of
such a problem. Will try it now ...

PS: Compared to previous releases of git the import is at least 10 times
faster. Good job!
