189934 - When selecting Tools > Search > Messages Mozilla locks up in a 100% CPU loop

Status: RESOLVED DUPLICATE of bug 169777

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Barry Treahy]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2.1) Gecko/20021130
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2.1) Gecko/20021130

Something recently developed that is 100% reproducable now, and that is
everytime I want to search my messages using the Tools > Search > Messages,
Mozilla enters a 100% CPU loop and never returns (hours later) without any
dialog box appearing in response.  This wasn't an issue or a problem until this
week and no software or reg entries have been altered during this period; It
just started locking up.  As my luck has it, I have a dual processor, so Mozilla
is only killing one processor and not bringing my entire system to a halt...

Reproducible: Always

Steps to Reproduce:
1. Start e-mail client
2. Click on Tools > Search > Messages
3. Watch the CPU spin as nothing else happens...

Actual Results:  
Endless Process Looping

Expected Results:  
Produced a dialog box of search options

No talkback data gathered as Mozilla never actually crashes.  Oddly, if I
attempt to open the Java console, running 1.4se, the second processor enters the
loop.

Reporter:
Please close mozilla and rename the file "xul.mfl" in your mozilla profile.

Splendid!  That fixed it.  Can someone educate me as to what that file does and
perhaps why this occurred as we have another less frequent MZ hangs and I'm
wondering if this might be the general 'cure' and if so, are there any negative
side-effects that I should be cautious of?

Please zip the file (the old one)and send it to [e-mail]

This file is a cache for Mozilla UI language "XUL"
