Bug 295362

I'm having konqueror open with 3 tabs :

1.  ~/MyDocuments
2. ~/MyDocuments/my_file.dvi
3. ~/MyDocuments/my_file.dvi

(yes : two times the DVI file)

I'm using the "autorefresh" option, so that when I recompile
latex my_file.tex
konqueror reload the new dvi.

Sometimes, a tab do not refresh and closing it crashes konqueror. Here is the traceback :

Application: Konqueror (konqueror), signal: Segmentation fault

This time, it happened with a math course of 133 pages. Since my code is divided into tens of tex files, it will be difficult for me to give an example.
