188855 - GtkMozEmbed/Mozilla segfaults when called from different threads

Status: RESOLVED WONTFIX

(Core Graveyard :: Embedding: GTK Widget, defect)

Description

[Jami Pekkanen]

User-Agent:       Mozilla/5.0 Galeon/1.2.7 (X11; Linux i686; U;) Gecko/20021208 Debian/1.2.7-5
Build Identifier: Mozilla/5.0 Galeon/1.2.7 (X11; Linux i686; U;) Gecko/20021208 Debian/1.2.7-5

I'm not sure if GtkMozEmbed/mozilla embedding should even be thread safe, but it
would simplify my work a lot.

When I call gtk_moz_embed_load_url from another thread than one that created it,
Mozilla gives segfault in NSGetModule () from libnecko.so.

I don't have debugging symbols so the trace wouldn't be very helpful, but if you
can't reproduce this behavior, I'll compile it with the symbols and give the
backtrace.

Reproducible: Always

Steps to Reproduce:
See the testcase.

It's not designed to be thread safe.  Please proxy to the UI thread for
something like this.
