Description Gene Heskett 2003-01-13 01:34:02 UTC
Version:           kde-3.0.5a for RH8.0 useage (using KDE KDE 3.0.5)
Installed from:    Unlisted Binary Package
OS:          Linux

This kde install is the special rpm set for RH8.0, for version 3.0.5a.

Kwin segfaults with SIGINT_11 or some such, repeatable at will by winning a game of kmahjongg or sishen sho, or closing the last of a multiple windowed gedit session.  If it leaves me with an active shell, I can type "kwin &" and restore operation, else its ctrl-alt-bksp and restart X.
Which if I have other things going is a bit of a pita sinec all my work is lost at that point.

This has been a problem here since 3.0.2 and RH7.3 but is getting worse.

The system is stable otherwise and has achieved 2 month uptimes many times.  The video card is an nvidia gforce2 mx200, 32 meg video ram.

What happens if you switch your window decoration from BlueCurve to something else? 
Also, it'd probably be useful if you could provide a backtrace. 
Hint: you can restart kwin by switching to a plain terminal with Ctrl-Alt-F1, logging in, and 
running "DISPLAY=:0 kwin &" at the shell prompt.

This crash well predates the bluecurve 'phenomenon'.  Which is why I 
removed the rh8.0 kde install and have since installed 2 updates 
from the special for rh8.0 drawer at kde.org, now at 3.0.5a.

It was set to bluecurve as I hadn't changed that default. The 
decorations change as they should. I tried them all and left it at 
KDE-II as some of the others tend to cover up or render the 
titlebar stuff at very low contrast.

I've attached a couple of them.

Thats where I do the startx from in the first place, so it would 
have to be F2 or greater.

Nice to know, as that should rescue most of the crashes.

I've been trying to file this bug for a long time, 4 or 5 months but 
mozilla seems to be badly mis-configured here, it kept asking my 
filesystem for the cgi stuff that only exists on your site. I even 
downloaded and installed (well, tried to, there is no install 
instructs in the full package) the whole bugzilla.  Then I found 
that konqeror has come a long ways since the last time it crashed 
on me, and that worked.  Fairly fast, I even got java to work with 
it last night.  But I like the lizards presentation of other 
things, so if I could get some hints on fixing that cgi problem, 
I'd appreciate it.  It treats them as file instead of http.

Now, to see if I can figure out why kmails filters sorted this 
message to the JunqueMail drawer where I just now found it.
I expect a look at all headers will show that reason.

Well, the two problems could be unrelated. The backtraces you attached sure looks like it's a 
BlueCurve bug...  It'd be very nice to know whether the problem goes away now that you use 
BII. And if not, please attach the backtraces for the "new" crashes as well. 
 
Can't say muich about Mozilla, sorry, don't use it.

I will.

Not BII, but "KDE2 default" is in effect now.  I'll go play a game 
of shisen sho and see if it crashes when done, that, and kmahjongg 
are 100% crash generators, but the regular mahjongg doesn't.  And I 
lost a hours work with a gedit quit one of 2 windows operation last 
night.

Whats your fav browser?

It appears to be the 'bluecurve' bug ok, I've not been able to crash 
is since switching to 'KDE2 default'.  But lemme play for a day and 
make sure before we cancel it.

Comment 6 Gene Heskett 2003-01-14 21:32:35 UTC
I think we can close this bug, I haven't had a crash since switching away from the "bluecurve" window decorations.  The question then is:  Do we have to go thru all this again for the bluecurve bug, or is that one already cleared and just hasn't made a distribution medium yet? 
Comment 7 Maksim Orlovich 2003-01-15 05:01:47 UTC
I'll close this then. The BlueCurve bug doesn't belong here since it's in software written by and 
distributed by RedHat and not KDE. I've notified one of the RH packagers on IRC, but it might 
be a good idea to add a note about this in their bugzilla, since you seem to have a good way of 
reproducing it.

I tried that tonight after rxing this, but their bugzilla is just 
enough different that I was stuck in a loop of open new bug, get 
search screen, then list of stuff to file bug against, nothing for 
kwin or bluecurve there, click on new, or 'report new bug' repeat 
till disgusted.

So I sent bugzilla@redhat.com a quasi-poison pen email, detailing 
the exact conditions to demo the crash, and the fix, which is 
apparently get bluecurve 'out of the loop'.  I was surprised that 
konqeror couldn't deal with their bugzilla forms any better than 
that, and already knew that mozilla was a waste of time because it 
translates the http: cgi scripts to file: and of course they don't 
exist on my machine.  Thats probably something in the mozilla 
mimetypes config, but I have NDI (no damned idea) how to go about 
fixing that.  Not even a SWAG.   Which is of course a Scientific 
Wild Assed Guess.

I appreciate your looking into this so promptly, its been a pleasure 
to communicate with someone who actually knows what they're doing 
for a change.  Doubly appreciated since I assume from your name 
that english possibly is not your first language.  I don't speak 
any other languages, and at my age (68) I won't try, so when 
someone goes to the effort to learn my language so well, I have to 
tip my hat to those who do.

Thanks Harald.  But the bigger question to me is why couldn't I file 
that myself?  Unless I could assign it to a package name, it 
wouldn't let me past the package listing point, but kept looping me 
back around to that.  This was using konqueror since the mime types 
or something in mozilla want to translate all those http: cgi 
script stuffs into file: cgi stuffs, and of course they don't exist 
on my machine.  Its almost as if its made difficult just so we 
can't file bug reports, and I object to that, it should be easy, 
but its impossible.  Things like this do nothing to help your 
mother to be as comfortable with linux as she is uncomfortable with 
winderz and its constant emailed viri and crashing.
