192384 - Mangled prefs.js file causes freezes on "Save..." and sending mail

Status: VERIFIED WORKSFORME

(SeaMonkey :: Preferences, defect)

Description

[Sam Little]

User-Agent:       Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.3a) Gecko/20021210
Build Identifier: Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.3a) Gecko/20021210

This one is a bit odd and may be OS/2-specific, but I'm not sure. At some point
I lost the ability to save pages/files or to send or "send later" any mail. I
solved the problem by looking at the prefs.js file and noticing that the printer
settings for a new printer were mangled... not so bad that an error message was
produced when loading, but obviously screwy. See "Additional Information."

Reproducible: Always

Steps to Reproduce:
1. Try "Save Page As" or "Save link target as" in browser or "Send" or "Send
Later" in composed e-mail.

Actual Results:  
Mozilla freezes; CPU monitor pins at 100%; have to force brower closed.

Expected Results:  
File (of some sort) written to drive.

prefs.js *had*:

This was hand corrected to:

user_pref("print.printer_Epson_Stylus_Color_760_Inkjet_printer.print_in_color",

And everything worked fine again. It looks like the names were mangled from the
first time they were referenced (I back up my profiles directory every 12 hours
but only keep one a week after midnight Sunday), but the filing problems didn't
happen until possibly after the following error was caught in popuplog.os2:

The pref horkage was fixed a while back, on Dec. 20th in bug 185588
Interesting if it really causes all those other bugs you observed.
Do you have a copy of the broken file?

Attachment: Mangled prefs.js file that didn't cause problems described

Comment 5

[Sam Little]

I've added before, during and after problem versions of prefs.js file. I'm not
sure what the causality might be; I didn't really expect my fix to work, but it
did and that was the only change I made. <shrug>

Comment 6

[R.K.Aa.]

Checking if the prefs.js horkage is a red herring or not (suspecting dup of bug
169777)

If you backup the fixed prefs.js and restore the mangled one that caused the
bugs: Do the same bugs surface again?

If yes: If you quit moz, delete XUL.mfl, then restart (still using the mangled
prefs.js): Do you still see the bugs?

Comment 7

[Sam Little]

Doing as requested didn't seem to break anything, though the XUL.mfl file shrank
considerably (from 2,199,134 bytes to 1,535,776 bytes. 

I had a bug report open a while back that was resolved by forcing an XUL.mfl
rebuild and something I didn't report (didn't think about it that much, but
typing or pasting into mail replies, I could insert newlines in the quotebacks,
but the text would go other than where the cursor was(!)) could be considered
related behaviour.

All of my backups suggest my problems all occurred during the existence of a
particular XUL.mfl build, though things worked within the first two hours of
that build's existence. Odd that there was no rebuild after the SYS3190, but....

Thanks!

Comment 8

[R.K.Aa.]

Thanks. Then this was likely a duplicate of bug 169777, but resolving as WFM.
