188572 - Cannot open Preferences any more (nearly 100% CPU is used)

Status: VERIFIED DUPLICATE of bug 169777

(SeaMonkey :: Preferences, defect)

Description

[gbrinkmann]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021130
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021130

I cannot open the preferences any more. After clicking the menu item
"Preferences..." mozilla completely freezes, eating up all free CPU time.
Without choosing the prefs, everything else seems to work still fine.



Reproducible: Always

Steps to Reproduce:
I cannot describe how to reproduce this. In my case it happens every time.
Yesterday it worked where i did change the font-size (in "Appearance" section).





I did try to open the prefs after i manually deleted prefs.js and user.js but
this did not change anything.

Attachment: "strace -p" of running mozilla-bin process

I do not know if this helps. This is a part of an strace output of the running
mozilla-bin process. The line

read(13, "", 8192)			= 0

is repeated endlessly.

This is quite helpful, actually. Can you please try renaming the XUL.mfasl or
XUL.mfl to something else, and try to reproduce the bug?

That file is a cache that can become corrupt. Renaming it forces Mozilla to
rebuild it.

_If_ that fixed the problem, send a copy of the file (zipped if it is big) to
[e-mail]

The filename on Linux is XUL.mfasl. Duplicate of bug 169777.

Removing the file XUL.mfasl did help. Thank you very much. The file size was
3351888 bytes. I will send it to the given address now...
