This happens if an unknown user account is found in the Subversion log. If I do not provide svn.authorsfile at all, it doesn't crash.

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?

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

"svn-git fetch" fails on this as well, strange ... The hook scripts or the property added by "svnsync init" are not responsible, right? > > Are you sure this isn't the regular svn 1.5.x crash?

I tried to reproduce it with a simple svn repository instead of my larger (not public) one but failed. What further information do you need? Is there any way to obtain more debug info? Jens ```
