Hi, after compiling gnash I have tried several files and all result in a
black screen.

I have checked the file with gparser and this one seems to understand
the file perfectly as it displays information that seems ok.

When I launch gnash with gdb, I obtain that :

(gdb) run
Starting program:
/home/grdscarabe/Developpement/amsn/plugin-winks/bin/gnash
Creative_Commons_-_Remix_Culture.swf
[Thread debugging using libthread_db enabled]
[New Thread 16384 (LWP 29296)]
[New Thread 32769 (LWP 29299)]
[New Thread 16386 (LWP 29300)]
[New Thread 32771 (LWP 29301)]

... I still have the black screen ... but nothing move ... it seems that
the application hangs !

I finally run it with strace to obtain informations :
I obtain a lot of : _llseek(9, 7101601, [7101601], SEEK_SET) = 0 ; I
don't know if it is normal or not.
The application finally hangs on :

writev(8, [{"\216\1\25\0\1\0\0\0", 8},

gettimeofday({1137046995, 512358}, NULL) = 0

The shortkeys CTRL+Q and others do not work and I have to kill the program.

I have tried with several files, including some of the directory
testsuite but they all do the same things (exactly). I guess the
programm read the begining of the swf file as the window has the good
size, but I don't know what happen then !

Adding the configure option --enable-pthreads fix the problem. Sorry to
bother you with this long message, but it is just in case that it is
something not expected ...
