User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040206 Firefox/0.8
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a1) Gecko/20040520
On writing text in a simple input text box writing 2 consequetive LamAlef
characters or with a short distance apart causes the following:
-In Mozilla 1.7b/1.8a/ Nightly Build The browser stops responding for 30 seconds
the first time the sequence is encountered. It resumes working normally
afterwards and if the sequence is encountered again it responds normally
-In Mozilla 1.6, X11 Crashes completely...
This Occurs on All Our Machines (30+) with different hardware configuration,
They All Have Linux Redhat 9 installed...
I tried the same sequence on Windows 2000 Professional SP4 with the same
versions and the problem doesn't occur.
Reproducible: Always
Steps to Reproduce:
1.Open Mozilla on linux
2.Open an Html page with a simple input:
<body>
<INPUT type="text">
</body>
3. Use this textbox to enter any of the following sequences:
الاسلام
صلاح شعلان
لالا
Actual Results:
ِAs I said, On 1.7b/1.8a/Nightly, Mozilla stopped responding for about 30 secs
the first time the sequence is entered, working normally afterwards. If I close
and reopen the browser, the problem occurs again...
Expected Results:
this sequences should not cause crash/irresponsivenesss

Arabic Charachters didn't display correctly in my steps to reproduce,
Simply Type 2 consquetive LamAlef (Lam then Alef then Lam then Alef) charachters
in step 3...

can you attach a testcase (given it can crash when the characters are already in
the input box) ? I don't have any arabic knowledge and am not sure how to get
these characters on an english Linux box.

Ok, unfortunately, a textbox with the value already set to the sequence doesn't
cause the problem (I guess it's the input), so an HTML file will not help
If this helps, Here is a UTF-8 Text File, copying and Pasting from it into the
input box causes the problem (I tried it)

This Week, We tried to recreate the bug on a Linux Mandrake 10 box,
It didn't occur on all mozilla versions, so I guess this is either X11 Version
or Redhat problem.
Mandrake 10 Versions
Kernel = 2.6.3-7mdk
XFree86 version = 4.3.0.1
Redhat 9 Versions (where the problem occured)
Kernel = 2.4.20-8
XFree86 version = 4.3.0 (Red Hat Linux release: 4.3.0-2)
