[Bug 1050628] [NEW] apache2 with mod_dav_svn and "SVNAutoversioning on" crashes of create directory

Thu Sep 13 20:59:39 UTC 2012

Public bug reported:

I've been using apache2+mod_dav_svn with "SVNAutoversioning on" before
on older Ubuntu servers with Subversion 1.4.6 without problems.

Now i've installed Ubuntu 12.04 and when i try to create a directory
with my webdav client (Mac OSX Finder) i get a permission denied message
- but the directory is created anyway.

I've located the problem to the MKCOL (create directory) command. If i
telnet to apache on port 80 and send the command MKCOL /mynewdirectory
HTTP/1.1\nHost: myexample.com the connection closes and i can see in the
apache error_log that the apache child process dies.
