crash when clicking on some links

[Corsaire]

Binary package hint: seamonkey

After starting SeaMonkey OK, crashes when opening some pages.

No link to report halas, concerned is a CMS intranet site. That I can tell however is that the browser and the server exchange informations in a PHP like fashion to generate a dynamic page

Worked OK until now (since early versions of Ubuntu I can't recall)

On my system it is reproducible when composing or replying to a message in Mail&Newsgroups.
See Launchpad bug 739995
Removal of libspellchecker.so helps a lot as this component seems to be optional.

[Corsaire (stranche)]

I confirm, when I remove /usr/lib/seamonkey-2.0.11/components/libspellchecker.so Seamonkey doesn't crash anymore

[Chinmay Rajhans (rajhanschinmay)]

I am also having the same problem.

I removed this file.
/usr/lib/seamonkey-2.0.11/components/libspellchecker.so

Before removing, I have kept a copy of it in case it is required later.

At the moment, error is not coming now.
