Description Indrajit Chatterjee 2008-12-09 16:50:10 UTC 
Version:           0.40 (using KDE 4.1.3)
OS:                Linux
Installed from:    SuSE RPMs

I executed kttsd and it sat in the system tray. Opened Okular to view a pdf. Selected the text to speech option in tools and kttsd crashed. Using Opensuse 11x64.

Hi! If you can reproduce the crash, you could install the debug enabled packages and provide a new backtrace. Read this page for the instructions:

Thanks!
Comment 3 Jacek Piskozub 2008-12-17 13:14:49 UTC 
I can confirm the same bug. Two different systems, both with Fedora 9, fully updated as of today.

The backtrace is:

Comment 4 Jacek Piskozub 2008-12-17 13:17:14 UTC 
By the way, from the backtrace this bug is almost certainly a dup of bug 164518.

This bug is about Okular (my backtrace is from using Okular) while the other is about Konqueror but the stack looks the same.
Comment 5 Jacek Piskozub 2008-12-17 13:23:02 UTC 
One more thing:

The package version number is: kdeaccessibility-4.1.3-1.fc9.i386
Comment 6 Christoph Feck 2009-05-24 17:52:54 UTC 
Jacek, comment #3 is indeed bug 164518.

Indrajit, did you read comment #2 ? If you can reproduce, can you show the full backtrace?
Comment 7 Indrajit Chatterjee 2009-06-12 00:39:50 UTC 
Hi- sorry for the late reply I have updated the Okular and the kspeech. Will let you know if the incident is reproduced.
Comment 8 Christoph Feck 2010-10-31 18:14:47 UTC 
In case the crash happens again, please add the backtrace. See comment #2 for more help.
Comment 9 Jeremy Whiting 2013-02-28 01:02:01 UTC 
This should no longer be possible.  I checked the backtrace code and getAppData in Speaker no longer can return a null object for Jovie to dereference which caused this crash (back when Jovie was KSpeech).

Reopen if you can recreate this issue somehow.
