Comment 1 Fabian 2009-07-21 15:13:36 UTC

I can reproduce the crash every time when I copy some xml in a document which was opend on startup and change the highlighting to xml.

Comment 2 Dario Andres 2009-07-21 15:24:47 UTC

Can you post some XML snippet that will cause Kate to crash? Thanks

Comment 3 Fabian 2009-07-21 16:17:35 UTC

Any XML I tried so far caused the crash eg:

<?xml version="1.0" encoding="UTF-8"?>
<xml>
	<test/>
</xml>

Comment 4 Dario Andres 2009-07-21 16:42:29 UTC

Here using:

Qt: 4.5.2 (KDE-Qt git commit 46a247a2c9a8c0c4456a02f6a0922d859d88fe76
        Date:   Fri Jun 26 13:45:37 2009 +0200)
KDE: 4.3.61 (KDE 4.3.61 (KDE 4.4 >= 20090717))
kdelibs svn rev. 999250 / kdebase svn rev. 999250
on ArchLinux i686 - Kernel 2.6.30.1

Opening Kate, pasting the provided XML snippet and selecting the "XML" highlighting didn't crashed the application.

Comment 5 Fabian 2009-07-21 16:54:37 UTC

Did you past it in an existing document (with activated highlighting different to html) and then switch the highlighting.

It does not crash when I past it in a new document, only when I past it in an existing document, with some different highlighting already active.

Comment 6 Dario Andres 2009-07-21 17:01:53 UTC

Thanks for the hint:

I could reproduce the crash with the same setup as I described in comment 4

The steps are:

- Open Kate
- Open a HTML document.
The html page will be loaded and the highlightning automatically set to "HTML"
- Copy the XML snippet
- Select all the html text (Ctrl+A) and paste the XML snippet over it
Now the document is only the XML snippet
- Go to Tools/Highlighting/Markup/XML

Kate crashes. (with the same backtrace as comment 0)

Updating the title to reflect the discovery.
Regards

Comment 7 Dominik Haumann 2009-07-21 17:33:31 UTC

can reproduce.
