237974 - ~96% CPU utilization on paste

Status: RESOLVED WORKSFORME

(Thunderbird :: Mail Window Front End, defect)

Description

[Colin Sparrow]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

Let me preface this... I'm what you would consider the "targeted" Mozilla user.
I'm someone who knows enough about computers to have heard of and installed
Firefox as an IE replacement, yet I get irritated when Mozilla-esq products
don't work as advertised... That being, they're supposed to be better than their
MS counterparts.

Yes, Thunderbird is 0.5 release, so it's bound to be somewhat buggy. But time
and time again, I can reproduce this issue. Say you're creating an email for
your friend based on a webpage-- in my case, I'm cutting and pasting a bunch of
computer history from Firefox to Thunderbird, it freezes up and uses nearly all
CPU time.

Reproducible: Sometimes
Steps to Reproduce:
1. Run Firefox. Select some text and copy it.
2. Paste it into a new/reply/forward/etc. message in Thunderbird.
3. Lather, rinse, repeat. Eventually TB will muck up and freeze, hauling in a
92-96% CPU utilization cycle.

Actual Results:  
TB "froze", using all available CPU resources. (RAM allocation never changed,
but CPU pegged at 96%.)

Expected Results:  
It should've just accepted my paste command.

I had TB in HTML email mode. It would be nice to replace Outlook (no, not OE)
with TB... But the product just doesn't work at the moment.

Rather than trying to emulate Outlook functionality, in a perverse Ximiam
Evolution sort of way, may I suggest OS X Mail as a jumping point? It's far
superior.

But I really do appreciate the task-based dialogue boxes rather than the Windows
standards ones. (Save/Don't Save/Cancel vs. Yes/No/Cancel.)

Colin--Can you give some idea of how much data you are pasting when it freezes
on you?  Would you guess there is 100 characters or 20,000 characters or ? 
Specifically I'm looking for an answer like:  "I tried to paste about 300
characters at the end of the composer window which contained approximately 50
lines of text."  (Note: I'm not looking for precision but rather a ballpark of
how much data we are dealing with)

Do you know if this is a regression or if paste has never worked acceptably?

Sorry, this bug got lost (to me) in an email shuffle and a move. It can be
marked resolved, as it hasn't occured in some time now. Oh, and in re-reading my
initial report-- apologies for the tone. TB has been my main Win/Lin mail client
for some time now.
