Following further tests, to replicate start a Reply to the message, position cursor at start of message and hit enter.  Each hit of enter causes a 40 second processor lockup.
@Alan, if that does not do it could you try it in plain text mode?  I think from your screenshot you are in html.  I can't work out how to set Thunderbird to html format to try that myself.  It is probably hidden somewhere in plain sight.

** Description changed:

  To replicate, send an email to Thunderbird client containing a line of 40,000 'x' characters, from a client that does not split the lines.  In thunderbird attempt to reply to this email and it locks the processor at 100% for several minutes.  I may be necessary to start typing into the reply to trigger the effect.
  I have not tested to determine whether the fact that they are kisses embarrasses Thunderbird so that it gets all in a tizzy, or whether any long line would achieve the same effect.

+ Further information:
+ The problem is only seen when replying in text mode, reply in html format is ok.

Title:
  Long line of kisses locks up processor in Thunderbird

Status in “thunderbird” package in Ubuntu:
  New

Bug description:

In thunderbird attempt to reply to this email and it locks the processor at 100% for several minutes.  I may be necessary to start typing into the reply to trigger the effect.
  I have not tested to determine whether the fact that they are kisses embarrasses Thunderbird so that it gets all in a tizzy, or whether any long line would achieve the same effect.

  Further information:
  The problem is only seen when replying in text mode, reply in html format is ok.
