Your Bugzilla server is Windows? And did you customize/edit email templates? This would probably explain it.

Recently I have updated Bugzilla to version 4.2.2.
Running @ :
- Debian 2.6.26-27 
- perl 5, version 14, subversion 2 (v5.14.2) built for i486-linux-gnu-thread-multi-64int (with 53 registered patches, see perl -V for more detail)
- Apache/2.2.21 (Debian)

No templates were modified prior to bug occurred - after that, there is a chance I've may tried to solve it on my own ... but ... when upgrading to 4.2.2. I am almost certain I replaced all my files with one from original package.

Bug persists ... 
If you need any additional info like file list in my installation (with md5sum?) or any other info that may mater - just say :).

I run into the same issue at version 4.2.3.  I am sure I haven't changed any email settings and email templates.

The empty email body was caused by the email with the wrong MIME encoding format. I think

You can open the  attachment 604862 [details] with thunderbird email client. Then view the email source. You would find that all email content are there, But it can't be decoded correctly by the email client. 

I am not familiar with MIME encoding. But from the source of the email. I can see the plain text and MIME encoding text were mixed in the email body section. It's not the consistent MIME encoding for the whole email body.

I guess the mixture of plain text and MIME encoding confused the email client. Then only blank was displayed

I have figured out the root cause.
I said I haven't changed any email template in pre comment. But I was using localization bugzilla version. Actually the blank email body was caused by the email template  ".../template/$lang/default/email/bugmail-header.txt.tmpl".
Because there is a definition for the line break of email header. It must be "\r\n" instead of the linux "\n". When the email header template was localized, the line break was changed to "\n". It confused the email client and empty email body was displayed.

After I changed the line break for email header in the template from "\n" to "\r\n", The email body was displayed as normal.

Hope this help for you!

I am a bit confused. I don't use localization (my bugzilla displays in english), also "Language used in email" is set to "Site Default (en)". In file you are mentioning ("template/en/default/email/bugmail-header.txt.tmpl") there is no line containing "\n" or "\r\n"
