[PyQt] QtWebKit segfault if libflashplayer.so is in plugin searchpath

[Robin Wittler]

Hello,

if i execute the following short script and
./mozilla/plugins/libflashplayer.so exists, there will be a segfault.

(process:9213): GLib-GObject-CRITICAL **: 
/build/buildd-glib2.0_2.24.1-1-i386-84Pp4V/glib2.0-2.24.1/gobject/gtype.c:2706: 
You forgot to call g_type_init()

(process:9213): GLib-CRITICAL **: g_once_init_leave: assertion 
`initialization_value != 0' failed

(process:9213): GLib-GObject-CRITICAL **: g_object_new: assertion 
`G_TYPE_IS_OBJECT (object_type)' failed

syslog says:
Jun 22 22:08:45 wtf kernel: [286355.647328] python[9213]: segfault at 28 
ip b18415f5 sp bf9666a0 error 6 in 
libgdk_pixbuf-2.0.so.0.2000.1[b183b000+18000]

If i rename libflashplayer.so to libflashplayer.so.bak all is ok and the 
website will load. There is also no problem with gnash (the opensource 
flash variant).

I have tested this with the gtk implementation of webkit, works as it 
should. (see other script below)

PyQt4 Version is 4,7,3
sip version is 4.10.2

Maybe someone here could help me with this.

cheers,
Robin
