paragraphs running together

["Russell L. Harris" <rlharris hal-pc org>]

I'm running Balsa 2.0.13 and Gnome2 under Debian 'unstable' on a desktop 
Pentium system.

When composing a message, the line wrapping appears to work perfectly.

But when the message is sent, the blank lines between paragraphs tend to 
disappear, so that paragraphs are run together.  Also, some lines are 
broken early, rather than at the specified wrapping column.

The same phenomenon is observed when a message is postponed and then 
resumed; the blank lines between paragraphs tend to disappear.

Is this a common problem, or is my Debian installation pathological?
