Comment 86 for bug 401823

I still get crashes from FireFox every few days.
Before each crash, I see one or more messages like this:
 (firefox:5290): Gdk-WARNING **: XID collision, trouble ahead

The actual crash is usually a SEGV. I think that it is a null pointer dereference but I cannot be sure because GDB is unreliable with optimized code. (I have an example where gdb prints 0 for a pointer variable but when I look at the assembly code I see that that variable is not represented at that point in the code.)

I don't think my problem has anything to do with cairo because I don't find RenderBadPicture in any of the tracebacks. Am I being naive? Should I look for something else? I'm using an up-to-date Fedora 11 on x86-64; cairo-1.8.8-1.fc11.x86_64; no flash plugin.

I'm attaching a very long typescript of a firefox session that failed and a gdb of the resulting core file. Perhaps someone could tell if

I think that the Cairo problems are a different bug and should have a different bugzilla entry.

The original posting in this bugzilla entry describes a bug that I still think is real. I imagine that this is the bug that is afflicting me.

I'm attaching a very long typescript of a firefox session that failed and a gdb of the resulting core file. Perhaps someone could tell from this if what I've said in this comment is wrong.
