Segmentation fault on checkout, import and cleanup
Greetings subversionists.
I have recently been having some problems with svn which since a
upgrade (from the Debian package of subversion around version 1.0.3-1
(I'm not quite sure exactly which the previous version was, sorry) to
1.0.6-2) since when all checkout, import and cleanup actions in svn
fail with a segmentation fault.
I tried creating a new repository to import the data to (thereby
having a clean database), but while svn mkdir works fine, the svn
import fails with a segmentation fault.
Also, whenever I tried to commit changes to my old projects it also
produced a segmentation fault and the command svn cleanup (which the
svn commit command suggests when one tries to run it again) fails in
the same way.
All operations where tried via a file: URL on a LVM-based ReiserFS
file system. The computer is a TM5800 running Debian unstable.
Do you have any idea if I am doing something wrong or is this a bug in
subversion?
Some examples included below. Just ask if you want more of the output
or want to do some other test. In both examples the editor was started
and I could enter the commit-comment before the crash.
Regards
Marcus

If you're using a vendor's binary packages and basic functionality is
not working for you, you're best off taking it up with the vendor (i.e.
Debian, after ensuring that your system is up to date), not with the
upstream provider. This is doubly true if you're using
Debian-unstable. It's simply beyond the realm of possibility that we
would distribute a release where checkout, import, and cleanup always
seg fault.
I happen to know that a few weeks ago, Debian introduced a
binary-incompatible change to libapr0 by rebuilding it with large-file
support, breaking Subversion unless users upgrade the subversion package
as well.
