Description Davide Vernizzi 2005-03-21 10:57:58 UTC
Version:            (using KDE KDE 3.4.0)
Installed from:    Gentoo Packages
Compiler:          gcc CFLAGS="-O3 -mcpu=pentium4 -funroll-loops -pipe"
OS:                Linux

When I view a postscript file with konqueror it uses embedded kghostview, and when I come back with left or up arrow, konqueror crashes.

Comment 2 Rob Huls 2005-04-19 13:03:43 UTC
Probably this is still the same as bug number 95988. I have it here too. If I 
view *eps en *ps files in konqueror, by default it embeds karbon14. Viewing 
works, but if I use 'up' or 'back', konqueror crashes. Did so in KDE 3.3.2 
from Debian unstable, and also does so with KDE 3.4.0 compiled with 
Konstruct. Setting KGhostview as embedded viewer solves the problem, but is 
it not strange that the default viewer is set to karbon when all it does is 
crash?

regards,
Rob

Comment 5 Tim Beaulen 2005-08-25 21:20:12 UTC
I can not reproduce it although many people seem to be able to.

I tried opening several eps files in konqueror with an embeded karbon part, but I never got it to crash.

The backtraces suggest a problem in this function:

void
VToolController::unregisterTool( VTool *tool )
{
	// tool->name() is not valid in VTool destructor
	QDictIterator<VTool> it( m_tools );
	for( ; it.current(); ++it )
		if (it.current() == tool)
		{
			m_tools.remove(it.currentKey());
			return;
		}
}


More specifically, I think the problem is with the following line:
QDictIterator<VTool> it( m_tools );

Should there be a check to see if m_tools is not null?
Comment 6 Inge Wallin 2005-08-27 23:30:52 UTC
No, I don't think so.  The documentation of QDictIterator doesn't say anything about that, and it is not a pointer so it can't become null. I think the error is somewhere else.
Comment 7 Rob Buis 2005-12-18 19:05:00 UTC
Hi,

I can't reproduce this, we think the problem was solved somewhere along
the line, probably in konqueror. This means I'll close this bug. If
anyone can come up with a proper testcase that shows this bug is still
there, we should reopen this bug, please do not forget to attach the problematic .ps file if that is the case!
Cheers,

Rob.
