[Bug 146147] Re: [GUTSY] firefox crashed [@XQueryExtension] [@XInitExtension] [@XextAddDisplay]

Hi,
I've similar problem on my FreeBSD 7.0 and I think it's bug in gplflash-0.4.13 package.

Here is a dump:
#0  0x28d2bdc3 in thr_kill () from /lib/libc.so.7
#1  0x28ce1c69 in pthread_kill () from /lib/libthr.so.3

dpy is NULL when XShmDetach is called and that NULL is passed through.
File: gplflash-0.4.13/plugin/plugin.c 
        if (This != NULL) {
                pthread_mutex_lock(&synchro);
                if (This->timer) {
                        XtRemoveTimeOut(This->timer);
                        This->timer = 0;
                }
                if (This->fh) {
                        XShmDetach(This->dpy, &This->segInfo); // <-- line 254

There is no any checks if This->dpy can be NULL.

we read that 'GPLFlash2 is not maintained nor developed anymore', but I don't know if it's related to gplflash-0.4.13 as well.
