Description John Hudson 2009-12-29 20:57:43 UTC 
Version:           2.1.0 (using KDE 4.3.1)
OS:                Linux
Installed from:    openSUSE RPMs

Normally close (CTRL-W) closes the open file and shows the screen that enables me to open another file; but after the current file has been renamed with 'Save as,' the use of close crashes KWord.

Application: KWord (kdeinit4), signal: Segmentation fault

Comment 1 Thomas Zander 2010-02-01 20:12:39 UTC 
Using valgrind I noticed the actual bug happens a bit before and then leaves stuff in a state that makes it crash later, as observed.

The valgrind I did showed a possible bug in kdelibs; here is the valgrind output;

The way to reproduce this quickly;
* start kword with empty doc.
* press save. Save with the name 'a.odt', press Ok.
* press save-as. Save with name 'b.odt', press Ok
On the pressing of "Ok" the above error occurs.
