Description Andrey Borzenkov 2009-06-28 11:30:05 UTC 
Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

KDE 4.2.95/Qt 4.5.2 x86_64 as shipped by Mandriva. Flash 10.0.22 from Adobe, D-Bus 1.2.4.6permissive compiled with assertions enabled.

nspluginviewer (or better libflashplayer) crashed. The problem is, next time konqueror crashed as well in D-Bus assertion apparently attempting to connect to this instance over D-Bus.

Connections can go away; crashing application seems a bit too hard reaction.

Application: Konqueror (kdeinit4), signal: Aborted

Comment 1 Andrey Borzenkov 2009-06-28 11:34:48 UTC 
Hmm ... according to debug sources, line dbus-message.c:1071 is

DBusMessage*
dbus_message_new_method_call (const char *destination,
                              const char *path,
                              const char *interface,
                              const char *method)
{
  DBusMessage *message;

  _dbus_return_val_if_fail (path != NULL, NULL);
  _dbus_return_val_if_fail (method != NULL, NULL);

but backtrace claims method is valid != NULL. Confused.
Comment 2 Pino Toscano 2009-06-28 12:09:32 UTC 
Maksim: didn't you fix invalid QDBusObjectPath's few days ago?
Comment 3 Maksim Orlovich 2009-06-28 17:32:33 UTC 
re: comment #2: what I fixed was nspluginviewer crashing with an assert inside QDBus if it failed to open a plugin.

I think I should ask thiago about this one. @reporter: what Qt and libdbus versions are you using?
Comment 4 Andrey Borzenkov 2009-06-28 18:00:54 UTC 
(In reply to comment #3)
> @reporter: what Qt and libdbus
> versions are you using?

As stated:

KDE 4.2.95/Qt 4.5.2 x86_64 as shipped by Mandriva. Flash 10.0.22 from Adobe,
D-Bus 1.2.4.6permissive compiled with assertions enabled.

If more specific information is required, please tell me.
Comment 5 Maksim Orlovich 2009-06-29 01:40:37 UTC 
Yeah, sorry. Missed that --- was reading the report before my morning tea..

Anyway:
<thiago_home> SadEagle:
<thiago_home> #9  0x00007f112499ae89 in dbus_message_new_method_call (destination=0x18d40b8
<thiago_home> "org.kde.nspluginviewer-22279", path=0x0, interface=0x2e1e9b8
<thiago_home> "org.kde.nsplugins.Class", method=0x396fbe8 "newInstance")
<thiago_home> path=0x0 is the problem
<thiago_home> which means the object in frame 14 is not properly created
