Not really; did you have the preview active in the file saving dialog? If so, what if you disable it?

Sorry, I was in a hurry when I filed the bug, but yet would not want to
miss the opportunity to inform the bug tracker of a problem now that
it's so easy with the automatic bug tracking mechanism in KDE —
particularly as it was the first one I brought through (I had to
compile a lot with -ggdb and splitdebug on to generate useful stack
traces) ... and on top of that: without some routine you just don't know
what really is useful information to pass along.

I tried to reproduce the failure with and without preview on: 

The problem does not occur systematically, not even with preview on;
which leads me to suspect that it has to do with concurrency (maybe
a race condition), and that it may happen if I close Okular while it is
still saving the PDF copy... the files that crashed (3 in number) were
all downloaded VISA account reports — that might be another reason
(something foul in the PS-code? Still, the document showed up
flawlessly, and Okular only crashed immediately after closing the
frame).

I have preview off now and will add to the bug report if crashes still
occur.

Don't hesitate to ask more questions to pinpoint the problem.
Comment 3 Dario Andres 2010-04-09 15:10:58 UTC 
BTW, this is probably bug 213008; so with the Previews disabled it shouldn't happen...
Comment 4 Pino Toscano 2010-05-22 22:23:29 UTC 
Right, thanks Dario!
