Description Diederik van der Boor 2005-04-08 10:14:21 UTC 
Version:           unknown (using KDE 3.4.0 Level "b" , SUSE 9.2 UNSUPPORTED)
Compiler:          gcc version 3.3.4 (pre 3.3.5 20040809)

KGhostView crashes if dvi2ps updates the .ps file that's open in KGhostView. I'm using the "watch file" feature.

Here is the produced backtrace:

My ghostscript version is:
ESP Ghostscript 7.07.1 (2003-07-12)
Comment 1 Jens 2005-05-25 16:07:48 UTC 
Hello,
this bug seems still to be in 3.4.0 and it's related to Bug 79034 and Bug 55653.

I would guess that the only real way to close this bug is to enable Kghostview / KPDF to check the file integrity _before_ trying to load it. I.e. check if the PDF / Postscript file is not corrupt. I don't know if searching for an "%%EOF" marker at the end of the file will do the trick, but this might avoid waiting for a fixed time (after all, loading a corrupt PDF or Postscript file can happen all the time, not just during re-creation by e.g. pdflatex).
