Description Ian Chapman 2008-06-20 13:37:32 UTC 
Version:            (using KDE 4.0.5)
Installed from:    Fedora RPMs
Compiler:          gcc 4.3.0 
OS:                Linux

When selecting "Speak Text" from the tools menu in konqueror, a dialog box opens
which says:

"The DBUS call StartText failed."

Then kttsd segfaults.

This is on ppc32, I do not know if it occurs on i386 or x86_64. (Fedora BZ number: 451568)

Comment 1 Dario Andres 2008-12-07 23:55:25 UTC 
Have you experienced this bug again with a recent KDE version ( 4.1.3 / 4.2beta1 / 4.2svn)? Thanks :)
Comment 2 Jacek Piskozub 2008-12-17 13:19:09 UTC 
See bug 177313, an almost certain dup of this one (there the bug is in Okular, not Konqueror, but the stack trace looks the same to me).

konqueror crash log

I experience exactly the same error with KDE 4.1.3.
The "a say () D-bus call was not successful" error message is shown in konqueror, but this is not mentioned in the crash log. :)

Do not register D-Bus object until we are ready()
Comment 5 Christoph Feck 2009-05-24 08:39:19 UTC 
Dario, I am not sure if I got that D-Bus magic right, should we CC thiago?
Comment 6 Christoph Feck 2009-05-24 18:48:30 UTC 
SVN commit 972345 by cfeck:

Fix D-Bus related crash in kttsd

The problem was that kttsd registered its D-Bus /KSpeech object
as soon as the application started, without making sure that the
daemon is fully initialized.

When during initialization of the daemon a KMessageBox is put up
(asking the user if he wants to add talkers to make speech work),
that message box tries to connect to the speech daemon via a D-Bus
call.

We now delay the registration of the object until we are fully
initialized. The other option was to entirely remove the message
box (which is bad, as the user may want to know what he needs to
do to get speech work), or make the message box non-modal, which
I found too complicated...
