Okay, I have managed to reproduce the issue with a publicly available repository.

Bug#780246: libsvn-perl: Segfault when applying large commit through git-svn
Package: libsvn-perl
Version: 1.8.10-5
Severity: important
Tags: upstream
Hi,
when I use git-svn to clone or fetch from a repository, and the repository
contains a commit that modifies a large number of files, then perl will die
with a segfault when trying to apply that commit:
$ git svn fetch
A scenario-simulator/test/test-simulator.properties
A scenario-simulator/test/log4j.properties
...
[snip long list]
...
A
core-util/test/com/opencloud/util/concurrent/fibers/WhenUsingDefaultFiberFactory.java
A
core-util/test/com/opencloud/util/concurrent/TimingWheelExecutorTest.java
error: git-svn died of signal 11
$
This is 100% reproducible with the affected commits, making it essentially
impossible to fully clone these repositories. The only workaround I can think
of is doing a shallow clone starting at the next commit, which means you won't
get the full history.
I have attached a backtrace, and here is the output of running the command
with the perl debugger:

No, unfortunately not. But it is definitely not specific to the repository, I've had it happen with other (similarly non-public) repositories as well. The important point seems to be the number of modified files and/or lines in a commit.
