1.0.6 crashes on trailers.apple.com #171

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Build and install gnome-mplayer/gecko-mediaplayer/libgmk from svn (or 1.0.6 
tarballs or install RPMs from packman repo). 
2. Open any trailer from  trailers.apple.com in Firefox 11 or Chrome 18
3.

What is the expected output? What do you see instead?
Expected: Gnome-mplayer starts, loads the trailer and begins playback.
Actual: Gnome-mplayer starts and seems to disappear immediately, browser says 
"Quicktime plugin crashed". Syslog contains a line like below for each 
attempted trailer playback:

[ 9201.265071] gnome-mplayer[17795]: segfault at 1 ip 00007f4189c8ce6d sp 
00007fff0b1232c0 error 4 in libglib-2.0.so.0.3000.1[7f4189c27000+f6000]

What version of the product are you using? On what operating system?
1.0.6 compiled from sources on Firefox 8/Chrome 18 on openSUSE 12.1 for x86_64

Please provide any additional information below.

That site works for me as well. Can you perhaps provide a better backtrace?

How can I do that? I mean gnome-player is started by the browser and the 
crashes, what to I attach to?

Ok, I've set core size ulimit to unlimited, and got a core file from 
gnome-mplayer  with the following stack trace:

Core was generated by `/usr/bin/gnome-mplayer --controlid=44825'.

Also, I replaced the gnome-mplayer executable with the following script in 
order to run gnome-mplayer under valgrind. Valgrind logs are attached.
#!/bin/sh
exec valgrind /usr/bin/gnome-mplayer.x $* >/tmp/gnome_mplayer$$.log 2>&1

Can you try changing line 607 in gui.c from

gchar *iterurl;

to

gchar *iterurl = NULL;

And see if that fixes your problem. I believe the issue is due to the usage of 
an uninitialized pointer.
