Cookbook upload failures

I’m sure this has already been answered, but I couldn’t find much in the search.
Here’s what I’m seeing:

[chef@chef-app01 chef-repo]$ knife cookbook upload syslog_and_roll
Uploading syslog_and_roll [0.0.1]
/usr/lib/ruby/gems/1.8/gems/chef-0.10.6/lib/chef/checksum_cache.rb:174:
[BUG] Segmentation fault
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

Aborted (core dumped)
[chef@chef-app01 chef-repo] knife cookbook upload syslog_and_roll Uploading syslog_and_roll [0.0.1] upload complete [chef@chef-app01 chef-repo]

Happens about 15% of the time.

The search history I’ve seen on this issue seems to indicate that
updating to a newer ruby, like patchlevel 352, will help and/or
resolve it. But I’m already there.

Any ideas? Things I can do? Ways I can run the command to get better
logging of the failures?

Thanks all,
