Which version of webkit gtk are you using? Latest time i've tried with 1.0.1 i think i was getting https://bugs.webkit.org/show_bug.cgi?id=19309. See my trace at https://bugs.freedesktop.org/show_bug.cgi?id=16717#c1.

I'm using webkit r36283 from this week.
It was working with swfdec 0.7.4.
Comment 3 Riccardo Magliocchetti 2008-09-10 11:56:46 UTC
Ok, this is not the pdata being null but window->ws_info. Do you have the same stack trace?

I'm sorry I don't understand gdb logs but I guess there is no informations available there even if libswfdec-0.8-1-dbg is installed :(
Do I need a swfdec-mozilla debugging package ?

yes, it's segfaulting in the plugin.

Comment 6 Riccardo Magliocchetti 2008-09-11 05:24:28 UTC
Same happens with latest git of midori and webkit r36309. Webkit bug filed there:
https://bugs.webkit.org/show_bug.cgi?id=20779
Comment 7 Riccardo Magliocchetti 2008-09-30 06:01:06 UTC
Here's another one:

Comment 8 Riccardo Magliocchetti 2008-10-16 01:18:48 UTC
Both patches are landed in webkit svn, i'm updating and compiling right now. If it works fine fine out of the box i'm closing this as NOTOURBUG.
