383416 - Auto Spell checking hangs Thunderbird with words with many equal letters

Status: RESOLVED WORKSFORME

(Thunderbird :: Message Compose Window, defect)

Description

[Fernando Suarez Ornani]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; es-ES; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4
Build Identifier: Thunderbird 2.0.0.0 (20070326)

I have spanish & english dicts but this happens whichever is selected.

If I write 15 letters together and then try to add one more, strange results occurs when there are lots of equal letters (For example: "fooooooooooooooo";the position of the consecutive letters is of no importance as this happens with "oooooooooooooof", or with "ooooooofooooooo")

If only 2 letters are written (for example "abcdefghijklmoo") there is a small delay with Thunderbird "thinking". When I put more consecutive letters (for example "abcdefooooooooo") the delay extends for a much longer period. If I write too many equal letters, the program seems to hang (I didn't wait much more than 5 minutes and I have a Core2Duo with 2Gb RAM; one of the cores is at 100% and there's no I/O traffic)


Reproducible: Always

Steps to Reproduce:
1. Start a new message
2. type 15 equal letters
Actual Results:  
Thunderbird hangs up

Expected Results:  
Mark word as bad

Talkback is completely skipped! It doesn't catch the crash!

It works great on version 3.0a1pre (2007090104). Now there isn't any delay at all (not even a small delay present on previous version)
