Do you have access to a gcc-3.3x compiler? I never had that problem before and the code hasn't changed for the last 5 months. Moreover, the backtrace looks weird as the value for "precision" is different in every frame, while it should be the same.

Michael.

I did just recompile everything (LFS system). I used compiler gcc-3.4.3 with flags: -Os -march=pentium-m -msse2 -msse -mmmx -fomit-frame-pointer, except of course for gcc and glibc. Anyway, I got somehow the same phenomenon. I might want to consider a gcc-3.3 compiler, but what would I need to recompile, kprinter, qt, kde-libs, kde-base? It does not seem to be cups, X, nor any of the other linked libraries, does it?

I have recompiled the whole system using gcc-3.3.6 now kprinter does not crash anymore. Seems to be a compiler issue. Furthermore I do not suspect kprinter anymore to trigger the bug in gcc, but some X-library, as the same problem showed also using Samsung llpr, which is in no way linked to Qt or KDE libs.

Because kprinter does not seem to be guilty I mark bug as resolved.

A similar crash (SIGSEGV) appears on Mandriva 2005 ("Limited Edition Club")

Configuration: 
The CUPS server is on another machine.  If I configure a local CUPS server, the problem goes away.

I too have been having this problem since about the begining of the year (maybe KDE 3.2) and haven't found any resolution above - however I have stopped short of recompiling my whole system on a hope!

Like the original poster properties for the PDF distiller works ok as does properties for a real cups printer when kprinter is run as root.

Richard Chonak, would you please provide the version of your compiler?

Chris Bayley, could you please confirm that the KDE and Qt packages that you're using were compiled with gcc-3.3.5? ('cause I have 3.3.5-20050117 here and I can't reproduce the crash -- thus it's difficult to debug).

I'm running Mandriva Linux; I assume it's all built with the following
compiler:

$ gcc -v

Thanks for looking into the problem.

On my system (gentoo), gcc (GCC) 3.3.5-20050130 was compiled April 13,
libqt was compiled May 10, and kdelibs compiled Aug 1, is that
sufficient to imply that gcc (GCC) 3.3.5-20050130 was used for both qt
and kdelibs, or is there a definitive method to determine the gcc
version used to compile various apps ?

Thanks,
Chris

Do you want an strace of the Seg fault ?

Cristian Tibirna wrote:

[bugs.kde.org quoted mail]

Thanks Chris. The backtraces that I have are already saying more than what an strace could. What would help much more would be a backtrace gotten with a KDE compiled with debug symbols or, even better, a way to reproduce this crash reliably, so that _I_ can do it too. I never manage to get such a crash, not with the PPDs indicated by reporters, not with anything else.

I will try valgrind in this week-end.

Thanks.

Since the dependence of the crash on some compiler version is no more plausible, could everybody who still sees this crash provide me with their ~/.lpoptions file? Thanks.

Thanks to the latest report (comment #17) from Georg, I think I understand what happens.

The people that observe the not-so-easy-to-reproduce crash seem to have a "media=[SomePageSize],[SomeMediaType],[SomeInputSlot]" option in ~/.lpoptions on the corresponding line of the printer that crashes kprinter. The crash occurs because either one of these three options is missing in the ppd used for that printer. One obvious culprit could be the generic.ppd for postscript printers, that lacks both MediaType and InputSlot options.

I can't really tell how do you end up with those options in the first place, but, as a workaround, you could just remove the media=... option from your ~/.lpoptions for now.

I will commit a fix to 3.5 when the commit freeze is over and in the meanwhile I will try the deeper implications of what happens here.

Thanks for your patience and for your help.

File attached per request.

Thanks Cristian, that was certainly the cause of the problem for me!

Removing MediaType and InputSlot from ~/.lpoptions works for me. Thanks,
