187786 - printing or previewing a mail message hangs mozilla and drives CPU utilisation to 100%

Status: VERIFIED DUPLICATE of bug 169777

(SeaMonkey :: MailNews: Message Display, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021212

I have printed received mail messages in the past with no problem. Now whenever
I attempt to print or even preview a mail message mozilla hangs. I'm not aware
of any changes to mozilla installation in the meantime, or to underlying printer
installation.
CPU utilsation goes up to 100%. I cannot close the mozilla window (It comes up
with the extra windows close non responsive process dialogue, but even that will
not kill it of) and I have to kill mozilla from the task manager.
This only seems to affect mail - I can print/preview web pages without the
problem. It does not seem to be related to any particular mail message - it is
repeating with any message, including plain text (as opposed to html). Printing
to an Epson EPL-550 using standard Windows XP drivers. Printer is operational
for other programs.

Can you try this: Quit Mozilla (and Quickstart, if running)
Then delete the file XUL.mfl in your profile directory
(It's a cache and rebuilds after startup if missing)
Now restart. Any change?

Thanks for the extremely quick and effective response. That did indeed solve the
problem. I'm impressed.

It also solved another one - I had been having problems trying to create a new
suibfolder on any of my existing mail folders - The section "create as a
subfolder of" was blank. That has also been resolved by deleting the cache.

As far as operation of my system is concerned this one can be closed. I hope
there is enough information in that to help you find the offending bit of source
code.

Thank you, but there's quite a few of these hangs/freezes reported - all related
to window creation. XUL.mfl is the "usual suspect" these days.

Keep in mind the Installation Notes, however.

Resolving as dup of bug 169777. Also see bug 134576 and dependencies.
